Impaired implicit learning in adults with anorexia nervosa.

Objective: Cognitive alterations play an important role in the pathophysiology and treatment of anorexia nervosa (AN). Previous studies suggest that some implicit learning processes may be inhibited in AN. However, this has not yet been fully explored.

Gut Microbiome Composition and Its Association with Sleep in Major Psychiatric Disorders.

Introduction: Sleep disturbances are highly prevalent across most major psychiatric disorders. Alterations in the hypothalamic-pituitary-adrenal axis, neuroimmune mechanisms, and circadian rhythm disturbances partially explain this connection. The gut microbiome is also suspected to play a role in sleep regulation, and recent studies suggest that certain probiotics, prebiotics, synbiotics, and fecal microbiome transplantation can improve sleep quality.

Association of fibroblast growth factor 21 with alcohol consumption and alcohol liver cirrhosis.

Background: Fibroblast growth factor 21 (FGF21) is produced in the liver and binds to different complex receptor/coreceptor systems. Besides many other processes, FGF21 regulates the intake of simple sugars and alcohol. Increased levels of FGF21 decrease harmful alcohol intake in mice.

Exome sequencing of a Pakistani family with spastic paraplegia identified an 18 bp deletion in the cytochrome B5 domain of FA2H.

Hereditary spastic paraplegias (HSPs) are a diverse class of neurodegenerative disorders that mainly affect the corticospinal tract of the body and result in various clinical conditions such as lower limb spasticity and muscle weakness in the lower extremities. Worldwide, more than 70 chromosomal loci/genes have been reported to be associated with HSPs, out of which, six genes viz., and have been mapped in Pakistani families.
