Association between dietary -carotene intake with Parkinson's disease and all-cause mortality among American adults aged 40 and older (NHANES 2001-2018).

Background: The existing evidence concerning the correlation between dietary -carotene intake and Parkinson's disease (PD) is currently deemed insufficient. Thus, this research aims to investigate the relationship between dietary -carotene intake and both the prevalence of PD and all-cause mortality within the US (United States) population.

Methods: The research employed cross-sectional analysis and cohort studies utilizing data from 16,852 participants in the National Health and Nutrition Examination Survey (NHANES) spanning from 2001 to 2018.

Trends and hotspots on the relationship between gut microbiota and Parkinson's Disease: a bibliometric analysis.

Parkinson's disease (PD) is a neurodegenerative disorder that significantly impacts patients' quality of life. Recent evidence has highlighted a complex relationship between the gut microbiota (GM) and PD. Understanding this relationship is crucial for potentially targeting GM in PD treatment and expanding therapeutic options.

Association between serum potassium and Parkinson's disease in the US (NHANES 2005-2020).

Background: Evaluating the correlation between serum potassium and Parkinson's disease (PD) in US adults.

Methods: A cross-sectional study was conducted on 20,495 adults aged 40 years or older using NHANES data from 2005 to 2020. The study utilized one-way logistic regression and multifactorial logistic regression to examine the correlation between serum potassium levels and PD.

Trends and hotspots in non-motor symptoms of Parkinson's disease: a 10-year bibliometric analysis.

Non-motor symptoms are prevalent among individuals with Parkinson's disease (PD) and seriously affect patient quality of life, even more so than motor symptoms. In the past decade, an increasing number of studies have investigated non-motor symptoms in PD. The present study aimed to comprehensively analyze the global literature, trends, and hotspots of research investigating non-motor symptoms in PD through bibliometric methods.

Vitamin B6 as a novel risk biomarker of fractured ankles.

Ankle fractures are the most common intra-articular fractures. Osteoporosis is a common and frequent disease among the elderly with a poor prognosis and high risk of fractured ankles. However, the relationship between vitamin B6 and the incidence of fractured ankles in patients with osteoporosis is unclear.

Application of Robot Positioning for Cannulated Screw Internal Fixation in the Treatment of Femoral Neck Fracture: Retrospective Study.

Background: Femoral neck fracture is a common type of hip fracture. Conventional surgical treatment aims at fixing the fracture site with screws and then gradually promoting bone healing. A robot-assisted orthopedic surgery system is computer technology applied to surgical treatment.

Antisense expression of PKCalpha improved sensitivity of SGC7901/VCR cells to doxorubicin.

Aim: To explore whether antisense blocking of protein kinase C alpha (PKCalpha) would reverse multi-drug resistance (MDR) in the vincristine (VCR)-resistant human gastric cancer cell line SGC7901/VCR.

Methods: SGC7901/VCR cells expressing antisense PKCalpha, SGC7901/VCR/aPKC, were established by transfection with a recombinant plasmid reversely inserted with PKCalpha cDNA. Empty vector (PCI-neo)-transfected cell clones, SGC7901/VCR/neo, served as the control.

Reversal of multidrug resistance in vincristine-resistant human gastric cancer cell line SGC7901/VCR by LY980503.

Aim: To investigate the reversal effect of LY980503, a benflumetol derivative, on multidrug resistance in vincristine (VCR) -resistant human gastric carcinoma cell line SGC7901/VCR.

Methods: Cells of a human gastric cancer cell line, SGC7901, and its VCR-resistant variant, SGC7901/VCR, were cultivated with LY980503 and /or doxorubicin (DOX). The cytotoxicity of drugs in vitro was assayed by MTT method.

Expression of ATP7B in human gastric cardiac carcinomas in comparison with distal gastric carcinomas.

Aim: To analyze expression of ATP7B in gastric cardiac adenocarcinomas, its clinicopathologic significance, in comparison with distal gastric adenocarcinomas.

Methods: Immunohistochemical avidin-biotin peroxidase complex method was applied to detect the expression of ATP7B in 49 cases of cardiac carcinomas, the corresponding adjacent non-neoplastic epithelium and 55 cases of distal gastric carcinomas.

Results: The proportion of ATP7B positive samples in gastric cardiac carcinomas (51.

Methylation in esophageal carcinogenesis.

Genetic abnormalities of proto-oncogenes and tumor suppressor genes have been demonstrated to be changes that are frequently involved in esophageal cancer pathogenesis. However, hypermethylation of CpG islands, an epigenetic event, is coming more and more into focus in carcinogenesis of the esophagus. Recent studies have proved that promoter hypermethylation of tumor suppressor genes is frequently observed in esophageal carcinomas and seems to play an important role in the pathogenesis of this tumor type.

[Drug-resistant proteins in breast cancer: recent progress in multidrug resistance].

Breast cancer resistance protein (BCRP) is a new multidrug resistance-related transmembrane transporter. BCRP is a 655-amino acid, 72.6 kDa protein, localized in the plasma membrane.
