Nitrogen deficiency is a key constraint on crop yield. Cassava, the world's sixth-largest food crop and a crucial source of feed and industrial materials, can thrive in marginal soils, yet its yield is still significantly affected by limited nitrogen availability. Investigating cassava's response mechanisms to nitrogen scarcity is therefore essential for advancing molecular breeding and identifying nitrogen-efficient varieties.

Pancreatic β-cell damage is a critical pathological mechanism in the progression of obese type 2 diabetes mellitus (T2DM). However, the exact underlying mechanism remains unclear. We established an obese T2DM mouse model via high-fat diet feeding.

RrUNE12 binds to the RrGGP2 promoter to facilitate biosynthesis of AsA in Rosa roxburghii fruit. Furthermore, RrUNE12 upregulates antioxidant-related genes and maintains ROS homeostasis, thereby improving tolerance to salt stress. L-ascorbic acid (AsA) plays an essential role in stress defense as a major antioxidant in plant cells.

Mitochondrial quality control is crucial for the homeostasis of the mitochondrial network. The balance between mitophagy and biogenesis is needed to reduce cerebral ischemia-induced cell death. Ischemic preconditioning (IPC) represents an adaptation mechanism of CNS that increases tolerance to lethal cerebral ischemia.

Summary: A 17-year-old girl presented with recurrent attacks of acute pancreatitis, associated with severe hyperglycemia and hypertriglyceridemia, despite being on intensive insulin therapy for the last 10 years. She had severe acanthosis nigricans, generalized loss of subcutaneous fat and prominent veins over extremities. The serum levels of glucose and triglyceride did not reduce significantly, even with maximally tolerated doses of metformin (2 g), pioglitazone (45 mg) and fenofibrate (160 mg), not uncommonly seen in poor rural families in West Bengal, India.
