A combination regimen of Intravitreal clindamycin with dexamethasone, systemic co-trimoxazole and steroids for macular Toxoplasma retinochoroiditis in immunocompetent cases.

Purpose: To study the role of intravitreal clindamycin with dexamethasone as an adjuvant to systemic co-trimoxazole and steroids in macular Toxoplasma retinochoroiditis.

Methods: Retrospective study of Toxoplasma retinochoroiditis cases from January 2014 to December 2021 treated with a combination of oral and intravitreal therapy in immunocompetent patients.

Results: 39 eyes of 39 patients were included in this study after meeting the inclusion criteria with the mean age of presentation being 25.

Occurrence and Risk Assessment of Tetracycline Residues in Layer Eggs in Haryana, India.

Antibiotics are extensively used in layer flocks for the prevention of diseases and to enhance their growth and production. However, their nonprudent use is leading to the occurrence of residues in eggs. The present study aimed at the detection of tetracycline group residues in egg samples collected from layer farms located in Haryana, India, and human health risk assessment.

Lingual Necrosis in the Setting of Giant Cell Arteritis.

Giant cell arteritis (GCA) is a medium-to-large vessel vasculitis most commonly affecting the aortic arch and carotid branches. Lingual necrosis is a rare complication of GCA caused by lingual artery vasculitis due to ischemia. A delay in diagnosis can result in irreversible complications such as tongue amputation.

Reliability of high-quantity human brain organoids for modeling microcephaly, glioma invasion and drug screening.

Brain organoids offer unprecedented insights into brain development and disease modeling and hold promise for drug screening. Significant hindrances, however, are morphological and cellular heterogeneity, inter-organoid size differences, cellular stress, and poor reproducibility. Here, we describe a method that reproducibly generates thousands of organoids across multiple hiPSC lines.

Effect of dietary fat source on the composition of the cecal microbiome in maturing broiler chicken.

Diet has been found to significantly influence gut microbiota throughout various life stages, and gut microbiota have been increasingly shown to influence host physiology, health, and behavior. This study uses 16S rRNA sequencing to examine the effects of six different fat-supplemented diets (canola oil, coconut oil, fish oil, flaxseed oil, lard, and olive oil) on broiler chicken cecal microbial composition and predicted function in comparison with a common and inexpensive fat source (poultry fat). Groups of broilers were fed each of these diets and then evaluated on day 41 and day 55 of age.
