Clinical and patient-reported outcomes between full-endoscopic and conventional parotidectomy: a prospective cohort study.

Objectives: This study investigates the clinical and patient-reported outcomes of full-endoscopic parotidectomy compared to the conventional approach.

Methods: Between July 2021 and December 2023, patients who underwent parotidectomy were prospectively enrolled and assigned to either the full-endoscopic parotidectomy group (Group I) or the conventional surgery group (Group II). Clinical outcomes were evaluated, and patient-reported outcomes were assessed using a Visual Analogue Scale and five FACE-Q scales.

[A Method of Aerosol Particle Number Size Distribution Inversed by PM Mass Concentration in PRD].

The aerosol particle number size distribution(PNSD) is of great importance in calculating atmospheric radiation and optics. It can effectively supplement the inadequate observation of PNSD using the widely known aerosol mass concentration (PM) measurement to invert PNSD. It would be valuable for research that needs PNSD data, like atmospheric visibility calculation.

Interaction of XRCC1 Arg399Gln Polymorphism and Alcohol Consumption Influences Susceptibility of Esophageal Cancer.

Background. To explore the correlation between the Arg399Gln polymorphism and susceptibility to esophageal cancer in Korean and Han Chinese individuals in Harbin, China, and its potential interaction with alcohol consumption. Methods.

Transcriptome Analysis Comparison of Lipid Biosynthesis in the Leaves and Developing Seeds of Brassica napus.

Brassica napus seed is a lipid storage organ containing approximately 40% oil, while its leaves contain many kinds of lipids for many biological roles, but the overall amounts are less than in seeds. Thus, lipid biosynthesis in the developing seeds and the leaves is strictly regulated which results the final difference of lipids. However, there are few reports about the molecular mechanism controlling the difference in lipid biosynthesis between developing seeds and leaves.

[Observation on analgesia effect of electroacupuncture during gynecologic outpatient operation].

Objective: To verify the feasibility of electroacupuncture analgesia applied to gynecologic outpatient operation.

Methods: Two hundred patients were randomly divided into an electroacupuncture analgesia group and an intravenous anesthesia group, 100 cases in each group. Operation types included artificial abortion, diagnostic curettage and remove of intrauterine divice.

[Genetic variation and association of prostaglandin F2alpha receptor (PTGFR) gene with sow maternal behaviors in a White Duroc x Erhualian resource population].

Maternal behaviors of sows around parturition are important for survival of newborn offspring. Failure to establish normal maternal bonds such as maternal infanticide and crushing often occurs in some individuals. It causes both significant economic losses to the pig industry and severe problems of piglet welfare.

Bis(2,2':6',2''-terpyridine)cobalt(II) bis-(tricyano-methanide).

The title complex, [Co(C(15)H(11)N(3))(2)](C(4)N(3))(2), is built up from discrete [Co(terpy)(2)](2+) cations (terpy is 2,2':6',2''-terpyridine) and [C(CN)(3)](-) anions. In the cation, the Co(II) atom is coordinated by two terpy mol-ecules, giving a distorted octa-hedral geometry. The tricyano-methanide anions are not directly coordinated to the Co(II) atom, but some weak C-H⋯N hydrogen bonds involving the terminal N atoms of the tricyaomethanide ions and the terpyridine H atoms link anions and cations building a three-dimensional network.

Changes of serum p53 antibodies and clinical significance of radiotherapy for esophageal squamous cell carcinoma.

Aim: To explore the relationship between serum p53 antibodies (p53-Abs) and clinicopathological characteristics and therapeutic effect in patients with esophageal carcinoma (EC), and to investigate sequential changing regularity of serum p53-Abs after radiotherapy.

Methods: The serum p53-Ab levels were detected in 46 EC patients and 30 healthy adults by enzyme linked immunosorbent assay (ELISA). The blood samples were collected on the day before radiotherapy and on the administration of an irradiation dose of 20 Gy/10 f/12 d, 40 Gy/20 f/24 d and 60 Gy/30 f/36 d after radiotherapy.

[Bioaccumulation of titanium dioxide nanoparticles in carp].

Analysis method for TiO2 nanoparticles in water and fish samples was set up using ICP-AES after dissolved by solution of sulphuric acid and ammonium sulphate. Meanwhile bioaccumulation of TiO2 nanoparticles was assessed by tests exposing carp (Cyprinus carpio)to TiO2 nanoparticles suspensions. The relative standard deviation (RSD) for water sample of 20.

Development of an ID-ELISA for the detection of Rice black-streaked dwarf virus in plants.

The Rice black-streaked dwarf virus (RBSDV) virion is composed of two layers of capsid proteins and 10 segments of double-stranded genomic RNA (S1-S10). Due to the fragility of the RBSDV outer capsid, it is very difficult to obtain intact virus particles for preparation of antiserum needed in virus detection. In this work, the major outer capsid protein (P10) encoded by S10 of RBSDV was expressed in Escherichia coli cells as a glutathione-S-transferase (GST) fusion protein.
