Shifts in the gut microbiota of sea urchin associated with the 2022 disease outbreak.

Introduction: In recent decades, Caribbean coral reefs have lost many vital marine species due to diseases. The well-documented mass mortality event of the long-spined black sea urchin in the early 1980s stands out among these collapses. This die-off killed over 90% of changing the reefscape from coral to algal-dominated.

Increased anxiety and emotional lability in a patient with SDHB gene mutation paraganglioma: a call to multidisciplinary approach.

Paragangliomas are neuroendocrine tumors that have the potential to secrete catecholamines. They have been linked to genetic mutations in the mitochondrial succinate dehydrogenase (SDH) complex. Patients can experience both physical symptoms and psychiatric symptoms like anxiety, depression, and psychosis.

Gut microbiota variation of a tropical oil-collecting bee species far exceeds that of the honeybee.

Introduction: Interest for bee microbiota has recently been rising, alleviating the gap in knowledge in regard to drivers of solitary bee gut microbiota. However, no study has addressed the microbial acquisition routes of tropical solitary bees. For both social and solitary bees, the gut microbiota has several essential roles such as food processing and immune responses.

The diagnostic performance of antimullerian hormone for polycystic ovarian syndrome and polycystic ovarian morphology.

Purpose: The diagnosis of polycystic ovary syndrome (PCOS) remains a challenge to clinicians due to heterogeneous clinical presentation and diagnostic criteria. This study investigated the utilization of Anti-Müllerian hormone (AMH) alone or replacing polycystic ovarian morphology (PCOM) in the PCOS diagnostic criteria.

Methods: A total of 401 women were categorised as PCOS (n:154), nonPCOS with polycystic ovarian morphology (PCOM) (n:105), and nonPCOS with normal ovarian morphology (NOM) (n:142).

Betulinic acid protects against ischemia/reperfusion-induced renal damage and inhibits leukocyte apoptosis.

The possible protective effect of betulinic acid on renal ischemia/reperfusion (I/R) injury was studied. Wistar Albino rats were unilaterally nephrectomized and subjected to 45 min of renal pedicle occlusion followed by 6 h of reperfusion. Betulinic acid (250 mg/kg, i.
