Mechanistic Episodes on SARS-CoV-2-Mediated Neurological Manifestations and Their Possible Therapeutic Interventions
J Environ Pathol Toxicol Oncol. 2022;41(1):85-98. doi: 10.1615/JEnvironPatholToxicolOncol.2021040128.ABSTRACTRecently, the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been critically recognized and spread rapidly on this planet. Considerable recognition of SARS-CoV-2 has been known with a range of viruses that are more capable to cause diseases in avian and mammals including humans. The virus was found as a main culprit for major defects in respiratory system and thereby caused severe acute respiratory syndrome disease. This has led to depict the mortality in human population. Nevertheless...

Molecular and pathological characterization of natural co-infection of poultry farms with the recently emerged Leucocytozoon caulleryi and chicken anemia virus in Egypt
AbstractIn the summers of 2018 and 2019, a disease outbreak stroke 25 broiler chicken farms and 3 broiler breeder farms in different Governorates in Egypt. The disease caused a mortality rate ranging from 3.2 to 9%. Postmortem examination showed petechial hemorrhage in the breast and thigh muscles, thymus gland, and peritoneal cavity and extensive hemorrhages in the kidneys. A total of 140 liver, kidney, lung, skeletal muscles, thymus, and spleen samples were collected. Twenty-eight pooled samples were created and examined by PCR and histopathological examination to identify the causative pathogens. All collected samples w...

Taxon-selective venom variation in adult and neonate Daboia russelii (Russell's Viper), and antivenom efficacy
Toxicon. 2021 Nov 6:S0041-0101(21)00305-6. doi: 10.1016/j.toxicon.2021.11.004. Online ahead of print.ABSTRACTMajor variations in venom composition can occur between juvenile and adult venomous snakes. However, due to logistical constraints, antivenoms are produced using adult venoms in immunising mixtures, possibly resulting in limited neutralisation of juvenile snake venoms. Daboia russelii is one of the leading causes of snakebite death across South Asia. Its venom is potently procoagulant, causing stroke in prey animals but causing in humans consumptive coagulopathy-a net anticoagulant state-and sometimes death resultin...

Differential coagulotoxicity of metalloprotease isoforms from Bothrops neuwiedi snake venom and consequent variations in antivenom efficacy.
This study broadens the current understanding about the adaptive role of the SVMPs, as well as highlights how the functional diversity of SVMP isoforms can influence clinical outcomes. Key Contribution: Our findings shed light upon the hemorrhagic and coagulotoxic effects of three SVMPs of the P-III class, as well as the coagulotoxic effects of SVMPs on human, avian and amphibian plasmas. Antivenom neutralised prothrombin-activating isoforms better than Factor X activating isoforms.

The cardiovascular system is critical for delivering O2 to tissues. Here, we examined the cardiovascular responses to progressive hypoxia in four high-altitude Andean duck species compared with four related low-altitude populations in North America, tested at their native altitude. Ducks were exposed to stepwise decreases in inspired partial pressure of O2 while we monitored heart rate, O2 consumption rate, blo...

Upstroke-based acceleration and head stabilization are the norm for the wing-propelled swimming of alcid seabirds RESEARCH ARTICLE
Anthony B. Lapsansky and Bret W. Tobalske
Alcids, a family of seabirds including murres, guillemots and puffins, exhibit the greatest mass-specific dive depths and durations of any birds or mammals. These impressive diving capabilities have motivated numerous studies on the biomechanics of alcid swimming and diving, with one objective being to compare stroke–acceleration patterns of swimming alcids with those of penguins, where upstroke and downstroke are used for horizontal acceleration. Studies of free-ranging, descending alcids have found that alcids accelerate in the direction of travel during both their upstrok...
