Background: Renal cell carcinoma (RCC) is characterized by its heterogeneity and the complexity of its tumor microenvironment. This study addresses the need to understand RCC at a cellular level, with a focus on its three main subtypes: clear cell (ccRCC), chromophobe (chRCC), and papillary renal cell carcinoma (pRCC).

Objective: This study aims to comprehensively characterize the cellular diversity and intercellular communication networks of RCC subtypes using scRNA-seq technology.

Background: Lenvatinib is an oral small molecule inhibitor approved for treating patients with unresectable hepatocellular carcinoma (HCC) worldwide. Increasing cell sensitivity to lenvatinib would be an effective method of improving therapeutic efficacy.

Methods: High throughput methods was used to scan the differentially expressed genes (DEGs) related to lenvatinib sensitivity in HCC cells.

Objective/background: Orexin has been shown to regulate the sleep-wake cycle, and it may play a major role in the pathogenesis of sleep disorders; however, its role in sleep disorders in pregnant women remains unclear. We aimed to assess the relationship between serum orexin-A (OXA) levels and sleep quality in pregnant women.

Patients/methods: This study comprised 214 enrolled pregnant women (poor sleep quality, n = 125; no poor sleep quality, n = 89).

Background: This study will investigate the effects of Spore Powder of Ganoderma Lucidum (SPGL) on CaSR and apoptosis-related proteins (ARP) in hippocampus tissue of epilepsy following dementia.

Methods: This study will retrieve all potential studies from both electronic databases (Cochrane Library, EMBASE, MEDLINE, CINAHL, AMED, and CNKI) and other literature sources to assess the effects of SPGL on CaSR and ARP in hippocampus tissue of epilepsy following dementia. We will search all literature sources from the inception to the present.

Feeding is vital for animal survival and is tightly regulated by the endocrine and nervous systems. To study the mechanisms of humoral regulation of feeding behavior, we investigated serotonin (5-HT) and octopamine (OA) signaling in , which uses pharyngeal pumping to ingest bacteria into the gut. We reveal that a cross-modulation mechanism between 5-HT and OA, which convey feeding and fasting signals, respectively, mainly functions in regulating the pumping and secretion of both neuromodulators via ADF/RIC/SIA feedforward neurocircuit (consisting of ADF, RIC, and SIA neurons) and ADF/RIC/AWB/ADF feedback neurocircuit (consisting of ADF, RIC, AWB, and ADF neurons) under conditions of food supply and food deprivation, respectively.

Animals have developed the ability to sense the water content in their habitats, including hygrosensation (sensing humidity in the air) and hydrosensation (sensing the water content in other microenvironments), and they display preferences for specific water contents that influence their mating, reproduction and geographic distribution. We developed and employed four quantitative behavioural test paradigms to investigate the molecular and cellular mechanisms underlying sensing the water content in an agar substrate (hydrosensation) and hydrotaxis in Caenorhabditis elegans. By combining a reverse genetic screen with genetic manipulation, optogenetic neuronal manipulation and in vivo Ca(2+) imaging, we demonstrate that adult worms avoid the wetter areas of agar plates and hypo-osmotic water droplets.

The off-response of ASH neurons had been overlooked until the microfluidic devices were introduced for in vivo imaging of neuronal activity in Caenorhabditis elegans. The mechanisms of ASH off-response were completely unknown. Here we monitored ASH off-response to CuSO4 stimulation by use of microfluidic device and genetically encoded calcium indicator (GECI) - Case12.

Objective: To research the maturation regulation of dendritic cells (DCs) pulsed with hepatocellular carcinoma (HCC) cell soluble antigens.

Methods: BCG HSP 70 was purified by SDS-PAGE electrophoresis and its biological activity was determined with ELISA. Phenotypes of DCs pulsed with antigens or with both antigens and BCG HSP 70 were analysed with flow cytometry.

Objective: To study the immune responses of lymphocytes after activated by dendritic cells (DCs) loaded with cytotoxicity T lymphocyte (CTL) epitope based peptide of human alpha-fetoprotein (hAFP, 218-226 LLNQHACAV).

Methods: Get high purity DCs by cultured plastic-adherent monocytes isolated from healthy donor of HLA-A2(+) peripheral blood with granulocyte-monocyte colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) for 7 days. Stimulate self-lymphocytes with DCs that loaded with CTL epitope based peptide of hAFP under the culture medium contains interleukin-2 (IL-2) for 7 days.
