Abstract Crosstalk between central nervous system (CNS) and systemic responses is important in many pathological conditions, including stroke, neurodegeneration, schizophrenia, epilepsy, etc. Accumulating evidence suggest that signals for central-systemic crosstalk may utilize glymphatic lymphatic pathways. The functionally connected to the meningeal system, together these pathways be involved distribution of soluble proteins clearance metabolites waste products from CNS. Lymphatic vessels dura meninges transport cerebrospinal fluid, part collected cervical lymph nodes, where solutes coming brain (i.e., VEGFC, oligomeric α-syn, β-amyloid) might activate a inflammatory response. There also an element time since immune strongly regulated by circadian rhythms, both dynamics have been shown change during day night. Understanding mechanisms regulating brain-cervical node (CLN) signaling how it affected diurnal or rhythms fundamental find specific targets timing therapeutic interventions.

Polycystic ovary syndrome (PCOS) is a unification of endocrine and metabolic disorders has become immensely prevalent among women fertile age. The prime organ affected in PCOS the its distressed functioning elicits disturbed reproductive outcomes. In ovary, macroautophagy/autophagy performs pivotal role directing chain events starting from oocytes origin until fertilization. Recent discoveries demonstrate significant autophagy pathogenesis PCOS. Defective follicular cells during different stages follicles observed ovary. Exploring pathways provides platform for predicting possible cause altered ovarian physiology this review, we have emphasized autophagy’s governing development under normal circumstances PCOS, including abnormalities associated with such as anovulation, hyperandrogenemia, disturbances, related abnormality. So far, few studies linked propose essential progression. However, detailed knowledge area lacking.

The circadian clock is an evolutionarily highly conserved endogenous timing program that structures physiology and behavior according to the time of day. Disruption rhythms associated with many common pathologies. emerging field medicine aims exploit mechanisms clock–disease interaction for clinical diagnosis, treatment, prevention. In this Essay, we outline principle approaches medicine, highlight development in selected areas, point out open questions challenges. Circadian has unambiguous health benefits over standard care but rarely utilized. It biology become integrated part translational research.

Individuals with type 2 diabetes (T2D) require a long-term dietary strategy for blood glucose management and may benefit from time-restricted eating (TRE, where the duration between first last energy intake is restricted to 8–10 h/day). We aimed determine feasibility of TRE individuals T2D. Participants T2D (HbA1c >6.5 <9%, window >12 h/day) were recruited pre-post, non-randomised intervention consisting 2-week Habitual period establish baseline intake, followed by 4-weeks during which they instructed limit all occasions 10:00 19:00 h on as many days each week possible.
