Small fiber peripheral neuropathy is a frequently encountered neurological disorder, which can be difficult to diagnose. In this article, the differential diagnosis of small fiber neuropathy is discussed, along with role of autonomic testing, skin biopsy, and quantitative sensory testing, in establishing a definitive diagnosis of small fiber peripheral neuropathy. Disorders of orthostatic intolerance, including postural orthostatic tachycardia syndrome (POTS), are also discussed, emphasizing diagnostic evaluation and a treatment approach to these disorders.

Painful diabetic neuropathy (PDN) is a challenging complication of diabetes with patients experiencing a painful and burning sensation in their extremities. Existing treatments provide limited relief without addressing the underlying mechanisms of the disease. PDN involves the gradual degeneration of nerve fibers in the skin.

Japanese quail () is a popular experimental animal model in scientific research. The present study investigated the effects of dietary multiple enzyme supplementation on growth performance, carcass characteristics, nutrient digestibility and small intestinal histomorphology in quails fed diets based on wheat and soya bean meal. A total number of 192 1-day-old quails were assigned to three treatments with 16 replicates in each and four quails replicate for 38 days.

2D materials feature large specific surface areas and abundant active sites, showing great potential in energy storage and conversion. However, the dense, stacked structure severely restricts its practical application. Inspired by the structure of bamboo in nature, hollow interior and porous exterior wall, hollow MXene aerogel fiber (HA-TiCT fiber) is proposed.

Fibromyalgia syndrome (FMS) presents a complex and challenging disorder in both the diagnosis and treatment, with emerging evidence suggesting a role of small fibre pathology (SFP) in its pathophysiology. The significance of the role of SFP in FMS remains unclear; however, recent evidence suggests degeneration and dysfunction of the peripheral nervous system, particularly small unmyelinated fibres, which may influence pathophysiology and underlying phenotype. Both skin biopsy and corneal confocal microscopy (CCM) have consistently demonstrated that ~ 50% of people with FMS have SFP.

The effects of microplastic (MP) accumulation in freshwaters on organisms and ecosystem functions are poorly understood, as are the roles of MP particle properties in regulating these effects. In freshwater microcosms, we quantified variation in microbial communities and ecosystem functions and compared effects of MP concentration (0, 1000, 50000 particles/kg), shape (sphere, fragment, fibre), and polymer (polyethylene, polyethylene terephthalate, polypropylene, polystyrene) with those of a model invertebrate consumer (Chironomus riparius). We detected multiple effects of specific MP properties, especially associated with MP fragments and fibres, and the polymer polypropylene.
