Integrative physicochemical and metabolic profiling of grain components related to nutritional quality in Yunnan hulled wheat and common wheat.

Background: Yunnan hulled wheat (YHW) is a semi-primitive wheat. It retains many nutrients lost in modern common wheat (CW) and has received increasing attention because it is proposed to have higher nutritional values than CW. However, information on the chemical composition and metabolic profiles of nutrient components in YHW and CW is limited.

Comparison of biological behavior of lacrimal gland adenoid cystic carcinoma with high-grade transformation cells.

Aim: To evaluate the differences between human lacrimal gland adenoid cystic carcinoma with high-grade transformation (LACC-HGT) primary cells cultured by high-grade transformation tissue and non-high-grade transformation (non-HGT) primary cells cultured by non-high-grade transformation tissue in proliferation, metastasis, drug susceptibility, and genes.

Methods: LACC-HGT primary cells were established by tissue block culture, and the 4 to 10 generation primary cells were selected as research objects. The cells were preliminarily identified by immunofluorescent staining.

Tripartite Crosstalk between Cytokine IL-1β, NMDA-R and Misplaced Mitochondrial Anchor in Neuronal Dendrites Is a Novel Pathway for Neurodegeneration in Inflammatory Diseases.

The mitochondrial anchor syntaphilin (SNPH) is a key mitochondrial protein normally expressed in axons to maintain neuronal health by positioning mitochondria along axons for metabolic needs. However, in 2019 we discovered a novel form of excitotoxicity that results when SNPH is misplaced into neuronal dendrites in disease models. A key unanswered question about this SNPH excitotoxicity is the pathologic molecules that trigger misplacement or intrusion of SNPH into dendrites.

CTLA-4 rs5742909 polymorphism and cervical cancer risk: A meta-analysis.

Background: Number of studies have been performed to evaluate the relationship between the cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) gene variant rs5742909 polymorphism and cervical cancer risk, but the sample size was small and the results were conflicting. This meta-analysis was conducted to comprehensively evaluate the overall association.

Methods: PubMed, Web of Science, Embase, China Biology Medical Literature database, China National Knowledge Infrastructure, WanFang, and Weipu databases were searched before July 31, 2018.

Chemoradiotherapy in combination with radical surgery is associated with better outcome in cervical cancer patients.

Objectives: To retrospectively assess the influence of radical surgery following concurrent chemoradiotherapy (CCRT) on outcomes in cervical cancer (CC) patients.

Methods: Patients diagnosed with cervical squamous cell carcinoma or adenocarcinoma (FIGO stages IB2 to IIB) at the Yinbin Second People's Hospital between September 2008 and September 2013, were included in this study. Patients were classified into 2 groups based on the treatment received: surgery group (CCRT plus radical surgery) and non-surgery groups (CCRT only).

WBSCR16 Is a Guanine Nucleotide Exchange Factor Important for Mitochondrial Fusion.

Regulated inter-mitochondrial fusion/fission is essential for maintaining optimal mitochondrial respiration and control of apoptosis and autophagy. In mammals, mitochondrial fusion is controlled by outer membrane GTPases MFN1 and MFN2 and by inner membrane (IM) GTPase OPA1. Disordered mitochondrial fusion/fission contributes to various pathologies, and MFN2 or OPA1 mutations underlie neurodegenerative diseases.

[Near infrared spectroscopy on-line and real-time monitoring of alcohol precipitation process of reduning injection].

Near infrared (NIR) spectroscopy as a kind of rapid process analysis technology has been successfully applied in Chinese medicine pharmaceutical process. In this research, the technology was adopted to establish the rapid quantitative analysis models of main indicators from the Lonicera japonica and Artemisia annua alcohol precipitation process of Reduning injection. On-line NIR spectra of 142 samples from alcohol precipitation process were collected and the content of main indicators for each sample were detected through off-line HPLC.

Spontaneous optic nerve compression in the osteopetrotic (op/op) mouse: a novel model of myelination failure.

We report a focal disturbance in myelination of the optic nerve in the osteopetrotic (op/op) mouse, which results from a spontaneous compression of the nerve resulting from stenosis of the optic canal. The growth of the op/op optic nerve was significantly affected, being maximally suppressed at postnatal day 30 (P30; 33% of age matched control). Myelination of the nerve in the optic canal was significantly delayed at P15, and myelin was almost completely absent at P30.

A novel method to study the local mitochondrial fusion in myelinated axons in vivo.

Mitochondrial remodeling (replication, fission/fusion) is a dynamically regulated process with diverse functions in neurons. A myelinated axon is an extension from the cell soma of a fully differentiated neuron. Mitochondria, once synthesized in the cell body, enter the axon displaying robust trafficking and accumulation at nodes of Ranvier to match metabolic needs.

Activity-dependent regulation of mitochondrial motility by calcium and Na/K-ATPase at nodes of Ranvier of myelinated nerves.

The node of Ranvier is a tiny segment of a myelinated fiber with various types of specializations adapted for generation of high-speed nerve impulses. It is ionically specialized with respect to ion channel segregation and ionic fluxes, and metabolically specialized in ionic pump expression and mitochondrial density augmentation. This report examines the interplay of three important parameters (calcium fluxes, Na pumps, mitochondrial motility) at nodes of Ranvier in frog during normal nerve activity.

WNT5A selectively inhibits mouse ventral prostate development.

The establishment of prostatic budding patterns occurs early in prostate development but mechanisms responsible for this event are poorly understood. We investigated the role of WNT5A in patterning prostatic buds as they emerge from the fetal mouse urogenital sinus (UGS). Wnt5a mRNA was expressed in UGS mesenchyme during budding and was focally up-regulated as buds emerged from the anterior, dorsolateral, and ventral UGS regions.

Action potentials induce uniform calcium influx in mammalian myelinated optic nerves.

The myelin sheath enables saltatory conduction by demarcating the axon into a narrow nodal region for excitation and an extended, insulated internodal region for efficient spread of passive current. This anatomical demarcation produces a dramatic heterogeneity in ionic fluxes during excitation, a classical example being the restriction of Na influx at the node. Recent studies have revealed that action potentials also induce calcium influx into myelinated axons of mammalian optic nerves.

Nicotinic acetylcholine receptors in mouse and rat optic nerves.

Receptor-mediated calcium signaling in axons of mouse and rat optic nerves was examined by selectively staining the axonal population with a calcium indicator. Nicotine (1-50 microM) induced an axonal calcium elevation that was eliminated when calcium was removed from the bath, suggesting that nicotine induces calcium influx into axons. The nicotine response was blocked by d-tubocurarine and mecamylamine but not alpha-bungarotoxin, indicating the presence of calcium permeable, non-alpha7 nicotinic acetylcholine receptor (nAChR) subtype.

Coupling of calcium homeostasis to axonal sodium in axons of mouse optic nerve.

Axonal populations in neonatal and mature optic nerves were selectively stained with calcium dyes for analysis of calcium homeostasis and its possible coupling to axonal Na. Repetitive nerve stimulation causes a rise in axonal [Ca(2+)](i) the posttetanus recovery of which is impeded by increasing the number of action potentials in the tetanus. This effect is augmented in 4-aminopyridine (4-AP; 1 mM), which dramatically increases the calcium and presumably sodium load during the tetanus.
