Effect of alloxan-induced diabetes on hepatic regeneration

Hepatic regeneration in alloxan-induced diabetic rats that underwent a 70% hepatectomy was compared to that of a series of non-treated rats. In diabetic rats, hepatic regeneration is lower and the liver reaches only 70% of the original weight ten days after hepatectomy. Analytical studies in these rats show a diminution of insulin and glucagon. Hepatic microcirculation as shown by measurements of CLV-CLV and CLV area undergoes changes which evolve at a different rate in the central and peripheral zones of the liver. These findings as well as the diminished hepatic regeneration may be attributed to the diminution of the insulin and glucagon values. Insulin and glucagon may be responsible for hepatic regeneration.

Physicochemical and microbiological stability of two news oral liquid formulations of clonidine hydrochloride for pediatric patients

Pediatric patients present changing physiological features. Because of the lack of land suitable for commercial management, pediatric specialties very often need to prepare extemporaneous formulations to improve the dosage and administration of drugs for children. Oral liquid formulations are the most suitable for pediatric patients. Clonidine is widely used in the pediatric population for opioid withdrawal, hypertensive crisis, attention deficit disorders and hyperactivity syndrome, and as an analgesic in neuropathic cancer pain. The objective was to study the physicochemical and microbiological stability and determine the shelf life of an oral solution containing 20?µg/mL clonidine hydrochloride in different storage conditions (5?±?3?°C, 25?±?3?°C, and 40?±?2?°C). Using raw material with excipients safe for all pediatric age groups, two oral liquid formulations of clonidine hydrochloride were designed (with and without preservatives). Solutions stored at 5?±?3?°C (with and without preservatives) were physically and microbiologically stable for at least 90?days in closed containers and for 42?days after opening. Two oral solutions of clonidine hydrochloride 20?µg/mL were developed for pediatric use from raw materials that are readily available and easy to process, containing safe excipients that are stable over a long period of time.     

Pneumocystis jirovecii pneumonia in two patients with systemic lupus erythematosus after rituximab therapy

New cases of Pneumocystis jirovecii pneumonia (PJP) have recently been reported in patients with systemic lupus erythematosus (SLE) after rituximab therapy. Several factors may contribute to susceptibility to P. jirovecii infection in this type of patients, including the immunological characteristics of the disease, the mechanisms of rituximab action, environmental factors, and the biological characteristics of the fungus. We report two patients with SLE who developed PJP after rituximab therapy.

Integration of Modern Molecular Tools with Geological Processes to Reveal Species Phylogeny,Biogeographical Niche Prediction,and Bio-Evolution

Nature is integrated, being simultaneously controlled by different natural aspects. Genetics, bioinformatics, biostatistics and geology are four diverse and broad scientific disciplines. But we believe that these can offer important insights into species distribution and evolution, if integrated. This perspective is grounded on a case study of the family Salvadoraceae, where species distribution and phylogeny show high correlation with the geological records. The results obtained from published and ongoing research indicate that we are pointing toward better visualizing the overlapping boundaries of these specific disciplines, which will be able to more accurately answer key evolutionary questions. We highlight: (1) the combined application of bedrock-soil geological data and bioinformatics to resolve evolutionary questions regarding species eco-distribution, niche prediction and bio-evolution; and (2) signifies the importance of relaxing boundaries between the disciplines to come to a better conclusion on species diversity and distribution-driven controls. Overall, we express and briefly explain our hypothesis to integrate modern analytical tools, viz., statistical correlation of geological data via. geo-statistics (Geo), and spatiotemporal biostatistics via. geo-informatics (Geo), with gene-based paleontological shreds of evidence, and sequence-based bioinformatics, to devise a practical analysis tool, namely “Geo² gene-bioinformatics”. We invoke the development of algorithms through computational-based programs that can provide useful correlations to understand evolutionary systematics and phylogeny, species distribution, and niche prediction.
