Optimization of efficiency of short-pulsed fast flow CO laser amplifier with dual-band and multispectral lines.

In this paper, we optimize the amplification efficiency of a nanosecond pulse CO laser in a fast flow amplifier using dual-band and multispectral lines techniques. Utilizing a six-temperature model and a random rotational relaxation model, we simulate the time-domain amplification process of dual-band and multispectral lines short-pulse seeds in a fast flow CO laser amplifier, analyzing the effects of input pulse fluence, pulse width, and spectral line composition on amplification efficiency. Compared to single-line 10P(20) amplification, the extraction efficiency of 10.

Solitary Interdigital Condyloma Latum in a Female Adolescent: A Case Report of an Unusual Form of Secondary Syphilis.

Condylomata lata are flat-topped, moist papules or plaques usually found in the anogenital area as cutaneous manifestations of secondary syphilis. Here, we present a unique case of a solitary interdigital condyloma latum of secondary syphilis in a 16-year-old female sex worker without other cutaneous findings. Sexual contact history, histopathology, including direct detection of , and serological tests were essential for the diagnosis of this case.

Changes of Gut Microbiome in Adolescent Patients with Chronic Spontaneous Urticaria After Omalizumab Treatment.

Here, we investigated differences in the gut microbiome of adolescent CSU patients before and after omalizumab treatment, which has not been previously reported.

Novel compound heterozygous mutation of in Gitelman syndrome co-existent with hyperthyroidism: A case report and literature review.

Background: Gitelman syndrome (GS) is a rare inherited autosomal recessive tubulopathy, characterized clinically by hypokalemia, hypomagnesemia, hypocalciuria, and metabolic alkalosis, and is caused by an inactivating mutation in . GS is prone to misdiagnosis when occurring simultaneously with hyperthyroidism. It is important to consider the possibility of other diseases when hyperthyroidism is combined with hypokalemia, which is difficult to correct.

Ferroptosis-Associated Classifier and Indicator for Prognostic Prediction in Cutaneous Melanoma.

Ferroptosis plays a critical role in different types of cancers, but the prognostic impact of ferroptosis in cutaneous melanoma remains lacking. Therefore, ferroptosis-related genes (FRGs) were firstly obtained from the FerrDb database and the differentially expressed FRGs were identified by the "limma" algorithm. Next, the prognostic differentially expressed FRGs were screened out by univariate Cox regression, which were subsequently used to cluster melanomas into two subtypes (clusters A and B).

Sensitivity of the Standard Chlamydia trachomatis Culture Method Is Improved After One Additional In Vitro Passage.

Background: Chlamydia trachomatis causes the most common bacterial sexually transmitted infection (STI) worldwide. Although highly sensitive nucleic acid amplification tests (NAATs) are used to routinely diagnose chlamydial infection, C. trachomatis isolation by cell culture is still preferred for legal cases and epidemiological studies because of its high specificity; however, the sensitivity of traditional two-passage diagnostic cultures is significantly lower than that of NAATs.

A Family-Based Association Study of CYP11A1 and CYP11B1 Gene Polymorphisms With Autism in Chinese Trios.

Autism spectrum disorder is a group of neurodevelopmental disorders with the higher prevalence in males. Our previous studies have indicated lower progesterone levels in the children with autism spectrum disorder, suggesting involvement of the cytochrome P-450scc gene (CYP11A1) and cytochrome P-45011beta gene (CYP11B1) as candidate genes in autism spectrum disorder. The aim of this study was to investigate the family-based genetic association between single-nucleotide polymorphisms, rs2279357 in the CYP11A1 gene and rs4534 and rs4541 in the CYP11B1 gene and autism spectrum disorder in Chinese children, which were selected according to the location in the coding region and 5' and 3' regions and minor allele frequencies of greater than 0.
