through Ghrelin Modulates Voltage-Gated Ca2+ Channels through Voltage-Dependent and Voltage-Independent Pathways in Rat Gastric Vagal Afferent Neurons [Article] By molpharm.aspetjournals.org Published On :: 2024-10-17T05:12:59-07:00 The orexigenic gut peptide ghrelin is an endogenous ligand for the growth hormone secretagogue receptor type 1a (GHSR1a). Systemic ghrelin administration has previously been shown to increase gastric motility and emptying. While these effects are known to be mediated by the vagus nerve, the cellular mechanism underlying these effects remains unclear. Therefore, the purpose of the present study was to investigate the signaling mechanism by which GHSR1a inhibits voltage-gated Ca2+ channels in isolated rat gastric vagal afferent neurons using whole-cell patch-clamp electrophysiology. The ghrelin pharmacological profile indicated that Ca2+ currents were inhibited with a log (Ic50) = –2.10 ± 0.44 and a maximal inhibition of 42.8 ± 5.0%. Exposure to the GHSR1a receptor antagonist (D-Lys3)-GHRP-6 reduced ghrelin-mediated Ca2+ channel inhibition (29.4 ± 16.7% vs. 1.9 ± 2.5%, n = 6, P = 0.0064). Interestingly, we observed that activation of GHSR1a inhibited Ca2+ currents through both voltage-dependent and voltage-independent pathways. We also treated the gastric neurons with either pertussis toxin (PTX) or YM-254890 to examine whether the Ca2+ current inhibition was mediated by the Gαi/o or Gαq/11 family of subunits. Treatment with both PTX (Ca2+ current inhibition = 15.7 ± 10.6%, n = 8, P = 0.0327) and YM-254890 (15.2 ± 11.9%, n = 8, P = 0.0269) blocked ghrelin’s effects on Ca2+ currents, as compared with control neurons (34.3 ± 18.9%, n = 8). These results indicate GHSR1a can couple to both Gαi/o and Gαq/11 in gastric vagal afferent neurons. Overall, our findings suggest GHSR1a-mediated inhibition of Ca2+ currents occurs through two distinct pathways, offering necessary insights into the cellular mechanisms underlying ghrelin’s regulation of gastric vagal afferents. SIGNIFICANCE STATEMENT This study demonstrated that in gastric vagal afferent neurons, activation of GHSR1a by ghrelin inhibits voltage-gated Ca2+ channels through both voltage-dependent and voltage-independent signaling pathways. These results provide necessary insights into the cellular mechanism underlying ghrelin regulation of gastric vagal afferent activity, which may benefit future studies investigating ghrelin mimetics to treat gastric motility disorders.

through Simplified Method for Kinetic and Thermodynamic Screening of Cardiotonic Steroids through the K+-Dependent Phosphatase Activity of Na+/K+-ATPase with Chromogenic pNPP Substrate [Article] By molpharm.aspetjournals.org Published On :: 2024-10-17T05:12:59-07:00 The antitumor effect of cardiotonic steroids (CTS) has stimulated the search for new methods to evaluate both kinetic and thermodynamic aspects of their binding to Na+/K+-ATPase (IUBMB Enzyme Nomenclature). We propose a real-time assay based on a chromogenic substrate for phosphatase activity (pNPPase activity), using only two concentrations with an inhibitory progression curve, to obtain the association rate (kon), dissociation rate (koff), and equilibrium (Ki) constants of CTS for the structure-kinetics relationship in drug screening. We show that changing conditions (from ATPase to pNPPase activity) resulted in an increase of Ki of the cardenolides digitoxigenin, essentially due to a reduction of kon. In contrast, the Ki of the structurally related bufadienolide bufalin increased much less due to the reduction of its koff partially compensating the decrease of its kon. When evaluating the kinetics of 15 natural and semisynthetic CTS, we observed that both kon and koff correlated with Ki (Spearman test), suggesting that differences in potency depend on variations of both kon and koff. A rhamnose in C3 of the steroidal nucleus enhanced the inhibitory potency by a reduction of koff rather than an increase of kon. Raising the temperature did not alter the koff of digitoxin, generating a H (koff) of –10.4 ± 4.3 kJ/mol, suggesting a complex dissociation mechanism. Based on a simple and inexpensive methodology, we determined the values of kon, koff, and Ki of the CTS and provided original kinetics and thermodynamics differences between CTS that could help the design of new compounds. SIGNIFICANCE STATEMENT This study describes a fast, simple, and cost-effective method for the measurement of phosphatase pNPPase activity enabling structure-kinetics relationships of Na+/K+-ATPase inhibitors, which are important compounds due to their antitumor effect and endogenous role. Using 15 compounds, some of them original, this study was able to delineate the kinetics and/or thermodynamics differences due to the type of sugar and lactone ring present in the steroid structure.

through Establishment of the First Institution-Based Poison Information Center in Nepal Through a Multilateral International Partnership By ghspjournal.org Published On :: 2024-10-29T12:28:39-07:00 ABSTRACTToxicological emergencies present a significant health challenge in Nepal. Despite the high burden, the country has inadequate formal toxicology training, medical toxicology expertise, and adequate poison control infrastructure. In recognition of this need, the Nepal Poison Information Center (PIC) was established as a collaborative effort involving local and international partners. Through a comprehensive partnership framework, the Nepal PIC provides 24 hours a day, 7 days a week expert guidance to health care workers, conducts educational webinars, and engages in research. Initial data from the pilot phase indicate successful consultation delivery. Challenges include bureaucratic hurdles and the need for sustainable funding. Despite these challenges, the Nepal PIC demonstrates early feasibility and potential for expansion into a comprehensive toxicology center, contributing to the advancement of clinical toxicology in Nepal. Long-term sustainability relies on governmental support and continued advocacy efforts. Full Article
through Documenting the Provision of Emergency Contraceptive Pills Through Youth-Serving Delivery Channels: Exploratory Mixed Methods Research on Malawi’s Emergency Contraception Strategy By ghspjournal.org Published On :: 2024-10-29T12:28:39-07:00 ABSTRACTIntroduction:Emergency contraceptive pills (ECPs) are effective and can be used safely at any age repeatedly within the same cycle. They are often favored by youth yet are underutilized. Private facilities can increase ECP access but present barriers including cost. Identifying effective public-sector ECP distribution models can help ensure equitable access. The Malawi Ministry of Health developed a strategy to improve ECP access in 2020. We documented ECP provision through select public, youth-serving channels recommended by the strategy: general and youth-specific outreach, paid and unpaid community health workers (CHWs), and youth clubs.Methods:We conducted this mixed methods study from November 2022–March 2023 in 2 rural districts (Mchinji and Phalombe) implementing the strategy. We conducted qualitative interviews with 10 national stakeholders, 46 providers, and 24 clients aged 15–24 years about ECP service delivery. Additionally, 25 providers collected quantitative tally data about clients seeking ECPs. We analyzed qualitative data using grounded theory and quantitative data descriptively.Results:Stakeholders and providers reported ECP uptake increased in geographies where the strategy was implemented, especially among youth. Providers documented 3,988 client visits for ECPs over 3 months. Of these visits, 26% were from male clients, 36% were from clients aged younger than 20 years, and 64% received ECPs for the first time. Across channels, youth club leaders and unpaid CHWs reported the most client visits per provider and served the youngest clients. However, no ECPs were dispensed during 29% of visits due to stock-outs. While many providers were supportive of youth accessing ECPs, most held unfavorable attitudes toward repeat use.Conclusion:ECP access should be expanded through provision in the studied channels, especially youth clubs and CHWs. However, to meet demand, the supply chain must be strengthened. We recommend addressing providers’ attitudes about repeat use to ensure informed method choice. Full Article
through Capacity-Building Through Digital Approaches: Evaluating the Feasibility and Effectiveness of eLearning to Introduce Subcutaneous DMPA Self-Injection in Senegal and Uganda By ghspjournal.org Published On :: 2024-10-29T12:28:39-07:00 ABSTRACTTraining health workers is one of the biggest challenges and cost drivers when introducing a new contraceptive method or service delivery innovation. PATH developed a digital training curriculum for family planning providers who are learning to offer subcutaneous DMPA (DMPA-SC), including through self-injection, as an option among a range of contraceptive methods. The DMPA-SC eLearning course for health workers includes 10 lessons with an emphasis on informed choice counseling and training clients to self-inject. In partnership with Ministries of Health in Senegal and Uganda, the course was rolled out in select areas in 2019–2020, including during the COVID-19 pandemic when physical distancing requirements restricted in-person training. We conducted evaluations in both countries to assess the practical application of this digital training approach for contraceptive introduction. The evaluation consisted of a post-training survey, an observational assessment conducted during post-training supportive supervision, and an estimation of training costs.In both countries, a majority (88.6% in Uganda and 64.3% in Senegal) scored above 80% on a DMPA-SC knowledge test following the training. In Senegal, where there was a comparison group of providers trained in person, those providers scored similar on the post-test to eLearners. Providers in both groups and in both countries felt more prepared to administer DMPA-SC or offer self-injection to clients after receiving a supervision visit (93%–98% of eLearners felt very prepared after supervision as compared to 45%–72% prior). The evaluation results suggest that digital approaches offer a number of benefits, can be cost-effective, and are most optimal when blended with in-person training and/or supportive supervision.

through Cannabinoid 2 Receptor Activation Protects against Diabetic Cardiomyopathy through Inhibition of AGE/RAGE-Induced Oxidative Stress, Fibrosis, and Inflammasome Activation [Special Section: Cannabinoid Signaling in Human Health and Disease] By jpet.aspetjournals.org Published On :: 2024-10-18T07:04:15-07:00 Oxidative stress, fibrosis, and inflammasome activation from advanced glycation end product (AGE)–receptor of advanced glycation end product (RAGE) interaction contribute to diabetic cardiomyopathy (DCM) formation and progression. Our study revealed the impact of β-caryophyllene (BCP) on activating cannabinoid type 2 receptors (CB2Rs) against diabetic complication, mainly cardiomyopathy and investigated the underlying cell signaling pathways in mice. The murine model of DCM was developed by feeding a high-fat diet with streptozotocin injections. After the development of diabetes, the animals received a 12-week oral BCP treatment at a dose of 50 mg/kg/body weight. BCP treatment showed significant improvement in glucose tolerance and insulin resistance and enhanced serum insulin levels in diabetic animals. BCP treatment effectively reversed the heart remodeling and restored the phosphorylated troponin I and sarcoplasmic/endoplasmic reticulum Ca2+ ATPase 2a expression. Ultrastructural examination showed reduced myocardial cell injury in DCM mice treated with BCP. The preserved myocytes were found to be associated with reduced expression of AGE/RAGE in DCM mice hearts. BCP treatment mitigated oxidative stress by inhibiting expression of NADPH oxidase 4 and activating phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/nuclear factor erythroid 2–related factor 2 (Nrf2) signaling. Also, BCP suppressed cardiac fibrosis and endothelial-to-mesenchymal transition in DCM mice by inhibiting transforming growth factor β (TGF-β)/suppressor of mothers against decapentaplegic (Smad) signaling. Further, BCP treatment suppressed nucleotide-binding domain, leucine-rich–containing family, pyrin domain–containing-3 (NLRP3) inflammasome activation in DCM mice and alleviated cellular injury to the pancreatic tissues evidenced by significant elevation of the number of insulin-positive cells. To demonstrate a CB2R-dependent mechanism of BCP, another group of DCM mice were pretreated with AM630, a CB2R antagonist. AM630 was observed to abrogate the beneficial effects of BCP in DCM mice. Taken together, BCP demonstrated the potential to protect the myocardium and pancreas of DCM mice mediating CB2R-dependent mechanisms. SIGNIFICANCE STATEMENT BCP, a CB2R agonist, shows protection against DCM. BCP attenuates oxidative stress, inflammation, and fibrosis in DCM via activating CB2Rs. BCP mediating CB2R activation favorably modulates AGE/RAGE, PI3K/AKT/Nrf2β and TGF-β/Smad and (NLRP3) inflammasome in diabetic cardiomyopathy. Full Article
through Digital Innovation to Grow Quality Care Through an Interprofessional Care Team (DIG IT) Among Underserved Patients With Hypertension [Original Research] By www.annfammed.org Published On :: 2024-09-23T14:00:14-07:00 PURPOSE The impact of digital health on medically underserved patients is unclear. This study aimed to determine the early impact of a digital innovation to grow quality care through an interprofessional care team (DIG IT) on the blood pressure (BP) and 10-year atherosclerotic cardiovascular disease (ASCVD) risk score of medically underserved patients. METHODS This was a 3-month, prospective intervention study that included patients aged 40 years or more with BP of 140/90 mmHg or higher who received care from DIG IT from August through December 2021. Sociodemographic and clinical outcomes of DIG IT were compared with historical controls (controls) whose data were randomly extracted by the University of California Data Warehouse and matched 1:1 based on age, ethnicity, and baseline BP of the DIG IT arm. Multiple linear regression was performed to adjust for potential confounding factors. RESULTS A total of 140 patients (70 DIG IT, 70 controls) were included. Both arms were similar with an average age (SD) of 62.8 (9.7) years. The population was dominated by Latinx (79.3%) persons, with baseline mean BP of 163/81 mmHg, and mean ASCVD risk score of 23.9%. The mean (SD) reduction in systolic BP at 3 months in the DIG IT arm was twice that of the controls (30.8 [17.3] mmHg vs 15.2 [21.2] mmHg; P <.001). The mean (SD) ASCVD risk score reduction in the DIG IT arm was also twice that of the controls (6.4% [7.4%] vs 3.1% [5.1%]; P = .003). CONCLUSIONS The DIG IT was more effective than controls (receiving usual care). Twofold improvement in the BP readings and ASCVD scores in medically underserved patients were achieved with DIG IT.

through Cat's Eye Camera Can See Through Camouflage By spectrum.ieee.org Published On :: Thu, 19 Sep 2024 14:30:06 +0000 Did that rock move, or is it a squirrel crossing the road? Tracking objects that look a lot like their surroundings is a big problem for many autonomous vision systems. AI algorithms can solve this camouflage problem, but they take time and computing power. A new camera designed by researchers in South Korea provides a faster solution. The camera takes inspiration from the eyes of a cat, using two modifications that let it distinguish objects from their background, even at night. “In the future … a variety of intelligent robots will require the development of vision systems that are best suited for their specific visual tasks,” says Young Min Song, a professor of electrical engineering and computer science at Gwangju Institute of Science and Technology and one of the camera’s designers. Song’s recent research has been focused on using the “perfectly adapted” eyes of animals to enhance camera hardware, allowing for specialized cameras for different jobs. For example, fish eyes have wider fields of view as a consequence of their curved retinas. Cats may be common and easy to overlook, he says, but their eyes actually offer a lot of inspiration.This particular camera copied two adaptations from cats’ eyes: their vertical pupils and a reflective structure behind their retinas. Combined, these allowed the camera to be 10 percent more accurate at distinguishing camouflaged objects from their backgrounds and 52 percent more efficient at absorbing incoming light.Using a vertical pupil to narrow focus While conventional cameras can clearly see the foreground and background of an image, the slitted pupils of a cat focus directly on a target, preventing it from blending in with its surroundings. Kim et al./Science AdvancesIn conventional camera systems, when there is adequate light, the aperture—the camera’s version of a pupil—is small and circular. This structure allows for a large depth of field (the distance between the closest and farthest objects in focus), clearly seeing both the foreground and the background. By contrast, cat eyes narrow to a vertical pupil during the day. This shifts the focus to a target, distinguishing it more clearly from the background.The researchers 3D printed a vertical slit to use as an aperture for their camera. They tested the vertical slit using seven computer vision algorithms designed to track moving objects. The vertical slit increased contrast between a target object and its background, even if they were visually similar. It beat the conventional camera on five of the seven tests. For the two tests it performed worse than the conventional camera, the accuracies of the two cameras were within 10 percent of each other. Using a reflector to gather additional light Cats can see more clearly at night than conventional cameras due to reflectors in their eyes that bring extra light to their retinas.Kim et al./Science AdvancesCat eyes have an in-built reflector, called a tapetum lucidum, which sits behind the retina. It reflects light that passes through the retina back at it, so it can process both the incoming light and reflected light, giving felines superior night vision. You can see this biological adaptation yourself by looking at a cat’s eyes at night: they will glow.The researchers created an artificial version of this biological structure by placing a silver reflector under each photodiode in the camera. Photodiodes without a reflector generated current when more than 1.39 watts per square meter of light fell on them, while photodiodes with a reflector activated with 0.007 W/m2 of light. That means the photodiode could generate an image with about 1/200th the light. Each photodiode was placed above a reflector and joined by metal electrodes to create a curved image sensor.Kim et al./Science AdvancesTo decrease visual aberrations (imperfections in the way the lens of the camera focuses light), Song and his team opted to create a curved image sensor, like the back of the human eye. In such a setup, a standard image sensor chip won’t work, because it’s rigid and flat. Instead it often relies on many individual photodiodes arranged on a curved substrate. A common problem with such curved sensors is that they require ultrathin silicon photodiodes, which inherently absorb less light than a standard imager’s pixels. But reflectors behind each photodiode in the artificial cat’s eye compensated for this, enabling the researchers to create a curved imager without sacrificing light absorption. Together, vertical slits and reflectors led to a camera that could see more clearly in the dark and isn’t fooled by camouflage. “Applying these two characteristics to autonomous vehicles or intelligent robots could naturally improve their ability to see objects more clearly at night and to identify specific targets more accurately,” says Song. He foresees this camera being used for self-driving cars or drones in complex urban environments.Song’s lab is continuing to work on using biological solutions to solve artificial vision problems. Currently, they are developing devices that mimic how brains process images, hoping to one day combine them with their biologically-inspired cameras. The goal, says Song, is to “mimic the neural systems of nature.”Song and his colleague’s work was published this week in the journal Science Advances.This article appears in the November 2024 print issue.

through Some Resources to Get You Through This Bumbling Attempted Coup By kristincashore.blogspot.com Published On :: Thu, 19 Nov 2020 15:55:00 +0000 U.S. District Judge Matthew W. Brann speaking to the only lawyer still willing to argue Trump's case in Pennsylvania, Rudolph Giuliani, on Tuesday:“You’re alleging that the two individual plaintiffs were denied the right to vote. But at bottom, you’re asking this court to invalidate more than 6.8 million votes, thereby disenfranchising every single voter in the commonwealth. Can you tell me how this result can possibly be justified?”Hello everyone. You might expect that while we are having to endure this comical yet terrifying attempted coup, my subconscious mind would be having a field day, giving me creative dreams as usual. But here's the dream I had Tuesday night, after that disgraceful show in Michigan: A Republican demagogue, anticipating his loss in the next election and wanting to prime public opinion, begins shouting as loud as he can about how the Democrats are going to steal the election. He loses the election. Then he tries to steal the election, again by accusing the Democratic victors of stealing the election. Rank-and-file Republicans fall in around him, supporting his baseless claims. A depressingly shocking number of voters believe him.Not a lot of creativity there, subconscious.For me, the most stressful part of all of this is how terrifying the GOP has become. A massive web of baseless lies that are believed by a gigantic number of people is terrifying. It's what my books are about. Of course, as a fantasy writer, I've always known I'm writing about real life. I found a recent episode of the Ezra Klein Show helpful in contextualizing the crisis that's been created by the Republican Party. In it, Ezra talks with Anne Applebaum, who studies authoritarianism. As a writer, I appreciated that the episode included a close study in character. The character of real people, of course, like Lindsey Graham and Laura Ingraham, but writers are naturally interested in the characters of real people. It's how we write believable imaginary people! Anyway, check it out if a grim perspective will help you get your feet on the ground. Don't check it out if what you need right now is comfort or reassurance, however. Those are valid needs too. And I have a couple of TV recommendations for that as well!About a month ago, I finished watching Jane the Virgin, which now has a permanent place in the upper echelon of my favorite TV shows of all time. It is so funny, so sweet and full of heart. It has political relevance, in a way that will make you feel hopeful. It's about families, writing, relationships between women, parenthood, magic, and it has characters you'll love so much that when you finally finish the last episode, you'll wander around feeling bereft for a while, or at least that's what happened to me. The plot is so absurd that you don't have to worry too much about bad things happening. The voiceover narrator is an absolute delight. I love this show so much, and if you've never seen it before, now might be the time!Also, last week I started watching Crash Landing on You, a South Korean TV drama in which a South Korean heiress has a hang-gliding mishap that drops her into the North Korean section of the DMZ. A very serious (and brooding) captain in the North Korean Special Police Force finds her and reluctantly decides to help her hide. It's very, very funny and keeps surprising me with its sweet moments — one of my favorite combinations in a TV show — and like with Jane, I'm falling for all the characters. Each episode seems to be incrementally longer than the last episode, to the point that my addiction to the show is interfering with the rest of my life, but I'm enjoying it too much to care. :o)By Source, Fair use,https://en.wikipedia.org/w/index.php?curid=62530475These are my recommendations for today… Hang in there, everyone. ????
