One positive upside of the past two months is how sheltering at home has all but emptied area animal shelters. It’s tough to get solid numbers nationally, but shelters in cities and regions all across America are reporting massive surges in animal adoptions. 

Even the steep increase in Google searches for “adopt a pet,” up a whopping 335 percent in April, proves what we probably all knew anyway — that in times of stress, having a furry friend is a huge comfort for millions.

Unfortunately, one of the downsides of the past two months is there are no trainers available to help whip some of these new family pets, particularly puppies, into shape. From barking and jumping to house training and scratching, The Complete Guide to Puppy and Dog Training Bundle is a full plan for getting the newest member of your family integrated into the house safely and sanely all by yourself.

The collection includes eight courses all geared toward getting a new dog or puppy behaving the right way. And if you’ve ever had any thoughts about starting a dog training business of your own, this coursework is a perfect starting spot.

Puppies: A-Z Guide to Puppy & Dog Training kicks off the learning, explaining the best way to train, teach and socialize your puppy so they grow into a joyful, well balanced, and well-behaved dog. 

Of course, most puppies each have their particular issues, so a handful of courses look more closely at some of the tactics for helping your puppy overcome certain challenging behaviors. Read the rest

I have a love/hate relationship with musical reaction videos. There are kids reacting to heavy metal (or The Beatles), vocal teachers and opera singers reacting to rock vocalists, millennials reacting to classic rock, and on and on. Some of these are quite moving, for instance, a 20-something hearing Zep's "Since I've Been Loving You" for the first time or a vocal teacher reacting to a Black Metal vocalist's cookie monster growl.

In these two videos, Heline, a classical flutist and music teacher, listens to Jethro Tull's Ian Anderson performing "Bouree" at a 1969 concert and then she listens and reacts to a performance from 1976.

I didn't realize that Anderson had only been playing the flute for a year and had no formal training at the time of the 69 video (their first tour). Heline can appreciate his chutzpah in the first performance and the fact that he's only been playing for a year(!), but is perhaps predictably critical of his playing. She is more impressed with what she sees and hears in the 76 performance.

Personally, I always thought his playing was inspired and his playing, vocalizing, singing and playing, and his other stage antics (the goofy one-legged stance) were a perfect example of "the street finding its own uses for things," using technology in ways in which it was never intended. As with all things artistic, your mileage may vary.

Secretary for Education Kevin Yeung today said the Government is confident that classes can resume on May 27.

Mr Yeung made the statement at a press conference this afternoon.

He said: “We are not announcing class resumption right away. We are giving advance notice of about three weeks for all the stakeholders to get prepared for the school resumption.”

The Government will continue to monitor the situation during this period and adjust the school resumption plan if necessary, he added.

"At this stage we are still pretty confident that we should be able to resume classes on May 27."

The presentation of peptides on class I human leukocyte antigen (HLA-I) molecules plays a central role in immune recognition of infected or malignant cells. In cancer, non-self HLA-I ligands can arise from many different alterations, including non-synonymous mutations, gene fusion, cancer-specific alternative mRNA splicing or aberrant post-translational modifications. Identifying HLA-I ligands remains a challenging task that requires either heavy experimental work for in vivo identification or optimized bioinformatics tools for accurate predictions. To date, no HLA-I ligand predictor includes post-translational modifications. To fill this gap, we curated phosphorylated HLA-I ligands from several immunopeptidomics studies (including six newly measured samples) covering 72 HLA-I alleles and retrieved a total of 2,066 unique phosphorylated peptides. We then expanded our motif deconvolution tool to identify precise binding motifs of phosphorylated HLA-I ligands. Our results reveal a clear enrichment of phosphorylated peptides among HLA-C ligands and demonstrate a prevalent role of both HLA-I motifs and kinase motifs on the presentation of phosphorylated peptides. These data further enabled us to develop and validate the first predictor of interactions between HLA-I molecules and phosphorylated peptides.

The prediction of metastatic properties from molecular analyses still poses a major challenge. Here we aimed at the classification of metastasis-related cell properties by proteome profiling making use of cutaneous and brain-metastasizing variants from single melanomas sharing the same genetic ancestry. Previous experiments demonstrated that cultured cells derived from these xenografted variants maintain a stable phenotype associated with a differential metastatic behavior: The brain metastasizing variants produce more spontaneous micro-metastases than the corresponding cutaneous variants. Four corresponding pairs of cutaneous and metastatic cells were obtained from four individual patients, resulting in eight cell-lines presently investigated. Label free proteome profiling revealed significant differences between corresponding pairs of cutaneous and cerebellar metastases from the same patient. Indeed, each brain metastasizing variant expressed several apparently metastasis-associated proteomic alterations as compared with the corresponding cutaneous variant. Among the differentially expressed proteins we identified cell adhesion molecules, immune regulators, epithelial to mesenchymal transition markers, stem cell markers, redox regulators and cytokines. Similar results were observed regarding eicosanoids, considered relevant for metastasis, such as PGE2 and 12-HETE. Multiparametric morphological analysis of cells also revealed no characteristic alterations associated with the cutaneous and brain metastasis variants. However, no correct classification regarding metastatic potential was yet possible with the present data. We thus concluded that molecular profiling is able to classify cells according to known functional categories but is not yet able to predict relevant cell properties emerging from networks consisting of many interconnected molecules. The presently observed broad diversity of molecular patterns, irrespective of restricting to one tumor type and two main classes of metastasis, highlights the important need to develop meta-analysis strategies to predict cell properties from molecular profiling data. Such base knowledge will greatly support future individualized precision medicine approaches.

For more than two decades naturally presented, human leukocyte antigen (HLA)-restricted peptides (immunopeptidome) have been eluted and sequenced using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Since, identified disease-associated HLA ligands have been characterized and evaluated as potential active substances. Treatments based on HLA-presented peptides have shown promising results in clinical application as personalized T cell-based immunotherapy. Peptide vaccination cocktails are produced as investigational medicinal products under GMP conditions. To support clinical trials based on HLA-presented tumor-associated antigens, in this study the sensitive LC-MS/MS HLA class I antigen identification pipeline was fully validated for our technical equipment according to the current US Food and Drug Administration (FDA) and European Medicines Agency (EMA) guidelines.

The immunopeptidomes of JY cells with or without spiked-in, isotope labeled peptides, of peripheral blood mononuclear cells of healthy volunteers as well as a chronic lymphocytic leukemia and a bladder cancer sample were reliably identified using a data-dependent acquisition method. As the LC-MS/MS pipeline is used for identification purposes, the validation parameters include accuracy, precision, specificity, limit of detection and robustness.

Anal squamous cell carcinoma is a rare tumor. Chemo-radiotherapy yields a 50% 3-year relapse-free survival rate in advanced anal cancer, so improved predictive markers and therapeutic options are needed. High-throughput proteomics and whole-exome sequencing were performed in 46 paraffin samples from anal squamous cell carcinoma patients. Hierarchical clustering was used to establish groups de novo. Then, probabilistic graphical models were used to study the differences between groups of patients at the biological process level. A molecular classification into two groups of patients was established, one group with increased expression of proteins related to adhesion, T lymphocytes and glycolysis; and the other group with increased expression of proteins related to translation and ribosomes. The functional analysis by the probabilistic graphical model showed that these two groups presented differences in metabolism, mitochondria, translation, splicing and adhesion processes. Additionally, these groups showed different frequencies of genetic variants in some genes, such as ATM, SLFN11 and DST. Finally, genetic and proteomic characteristics of these groups suggested the use of some possible targeted therapies, such as PARP inhibitors or immunotherapy.

Host Matt Egan clips us round the ear and tells us to listen up as we chat yet more tech and then some other stuff about tech. Consumer tech editor at PC Advisor Chris Martin lays down his definitive opinion after he went hands on with the Nintendo Switch this week, and why the company really should have had their star plumber ready in time for launch. Tamlin Magee, Online Editor at Computerworld UK then takes us through the odd goings on at Davos, and whether or not the elite can identify with what tech actually means to real working people. To round us up, Acting Macworld UK Editor David Price explains why app prices are going up in the UK for iOS users, and why it might - might - not be UKIP's fault. Sort of.

Atherogenic LDL particles are physicochemically and metabolically heterogeneous. Can bioactive lipid cargo differentiate LDL subclasses, and thus potential atherogenicity?  What is the effect of statin treatment? Obese, hypertriglyceridemic, hypercholesterolemic males (n=12; Lp(a) <10 mg/dL) received pitavastatin calcium (4mg/day) for 180 days in a single-phase, unblinded study. The lipidomic profiles (23 lipid classes) of five LDL subclasses fractionated from baseline and post-statin plasmas were determined by LC-MS. At baseline and on statin treatment, very small dense LDL (LDL5) was preferentially enriched (up to 3-fold) in specific lysophospholipids (lysophosphatidylcholine (LPC); lysophosphatidylinositol (LPI); lyso-platelet activating factor (LPC(O)); 9,0.2 and 0.14 mol/mol apoB respectively; all p<0.001 versus LDL1-4), suggesting  elevated inflammatory potential per particle. In contrast, lysophosphatidylethanolamine was uniformly distributed among LDL subclasses. Statin treatment markedly reduced absolute plasma concentrations of all LDL subclasses (up to 33.5%), including LPC, LPI and LPC(O) contents (up to -52%), consistent with reduction in cardiovascular risk. Despite such reductions, lipotoxic ceramide load per particle in LDL1-5 (1.5 - 3 mol/mol apoB; 3 - 7 mmol/mol phosphatidylcholine) was either conserved or elevated. Bioactive lipids may constitute biomarkers for the cardiometabolic risk associated with specific LDL subclasses in atherogenic dyslipidemia at baseline, and with residual risk on statin therapy.
