Catalytic asymmetric fragmentation of cyclopropanes.

The stereoselective activation of alkanes constitutes a long-standing and grand challenge for chemistry. Although metal-containing enzymes oxidize alkanes with remarkable ease and selectivity, chemical approaches have largely been limited to transition metal-based catalytic carbon-hydrogen functionalizations. Alkanes can be protonated to form pentacoordinated carbonium ions and fragmented into smaller hydrocarbons in the presence of strong Brønsted acids.

Phylogenetic analysis linked fatal neurologic disease in leopards (Panthera pardus) to Asia-5 lineage of canine distemper virus in Nepal.

Canine distemper virus (CDV) is responsible for a highly contagious and often fatal neurological disease that affects various carnivores, including domestic dogs. In Nepal, recent reports of CDV exposure and illness in leopards (Panthera pardus) have raised concerns about the transmission of the virus among domestic dogs and wild carnivores. To investigate the genetic lineage and spread of CDV, our study utilized archived post-mortem samples from four leopards that exhibited clinical signs suggestive of canine distemper infection.

Ventriculo peritoneal shunted patient undergoing laparoscopic procedure - A case report and review of the literature.

Introduction And Importance: It has been more than century since the establishment of relationship between the intracranial pressure (ICP) and intraabdominal pressure (IAP) was suspected and confirmed backed up by several studies. The studies clearly demonstrate a link and the positive correlation between the two.

Case Summary: 18 years old lady with previous history of ventricular peritoneal shunt during 6 months of age was planned for laparoscopic cholecystectomy.

A case report on posterior reversible encephalopathy syndrome (PRES) in an elderly female.

Introduction And Importance: Posterior reversible encephalopathy syndrome (PRES) is a medical condition characterized by symptoms such as headache, altered consciousness, visual abnormalities, seizures, and associated radiological vasogenic edema. The condition, as its name suggests, is generally reversible. PRES typically affects individuals around the age of 45 and is rarely seen in the elderly population.
