Background: Some herbal natural products play an important role in protecting organisms from the toxic effect of some xenobiotics. The present study was designed to evaluate the potential therapeutic effects of Ottelione A (OTTE) against carbon tetrachloride(CCl)-induced toxicity in mice.

Methods: Adult male Swiss albino mice were divided into six groups: group I was used as a normal control received olive oil; group II received DMSO; group III received OTTE; group IV received CCl in olive oil, (injected i.

Introduction: Peripheral nerve schwannomas are the most common nerve tumors. While they are efficiently treated with surgery, the risk of neurological complications, especially sensory deficits, remains debated.

Hypothesis: We postulate that rates of post-operative sensory deficits in peripheral schwannoma surgery are low and are not increased in schwannomas of the hand, in which preservation of discriminative tact is of prime functional importance.

Understanding transmission dynamics that link wild and domestic animals is a key element of predicting the emergence of infectious disease, an event that has highest likelihood of occurring wherever human livelihoods depend on agriculture and animal trade. Contact between poultry and wild birds is a key driver of the emergence of highly pathogenic avian influenza (HPAI), a process that allows for host switching and accelerated reassortment, diversification, and spread of virus between otherwise unconnected regions. This study addresses questions relevant to the spillover of HPAI at a transmission hotspot: what is the nature of the wild bird-poultry interface in Egypt and adjacent Black Sea-Mediterranean countries and how has this contributed to outbreaks occurring worldwide? Using a spatiotemporal model of infection risk informed by satellite tracking of waterfowl and viral phylogenetics, this study identified ecological conditions that contribute to spillover in this understudied region.

Article Synopsis
  • Limited information exists on the natural history of peripheral nerve schwannomas, prompting a study to investigate their growth rates and patterns in both sporadic cases and schwannomatosis.
  • The study analyzed records from 44 patients, revealing a median tumor size of 1.8 cm at diagnosis, with most tumors located in the lower limb and an average growth rate of 1.69 cm/year.
  • Findings showed that while most tumors grow slowly, some can grow rapidly, and further research is needed to understand the factors influencing tumor growth and to identify potential malignant transformations.

Article Synopsis
  • Aneurysmal bone cyst (ABC) is a harmless bone problem that can happen in kids and can sometimes cause bone fractures.
  • A study tested if using alcohol-based treatment for ABC is safe and works well, and it looked at 55 cases over several years.
  • Results showed that most patients felt better and had less pain, and the alcohol treatment is easy and could be a good option instead of surgery.
