The emerging concept of host specificity of Cryptosporidium spp. was exploited to characterize sources of fecal contamination in a watershed. A method of molecular forensic profiling of Cryptosporidium oocysts on microscope slides prepared from raw water samples processed by U.S. Environmental Protection Agency Method 1623 was developed. The method was based on a repetitive nested PCR-restriction fragment length polymorphism-DNA sequencing approach that permitted the resolution of multiple species/genotypes of Cryptosporidium in a single water sample.

We present a computational investigation into the fragmentation pathways of ethanolamine (CHNO, EtA), propanol (CHO, PrO), butanenitrile (CHN, BuN), and glycolamide (CHNO, GlA)-saturated organic molecules detected in the interstellar medium (ISM), particularly in the molecular cloud complex Sagittarius B2 (Sgr B2) and its molecular cloud G+0.693-0.027.

The Mutographs Cancer Grand Challenge team aimed to discover unknown causes of cancer through mutational epidemiology, an alliance of cancer epidemiology and somatic genomics. By generating whole-genome sequences from thousands of cancers and normal tissues from more than 30 countries on five continents, it discovered unsuspected mutagenic exposures affecting millions of people, raised the possibility that some carcinogens act by altering forces of selection in tissue microenvironments rather than by mutagenesis, and demonstrated changes to the direction of somatic evolution in normal cells of the human body in response to exogenous exposures and noncancer diseases.

Background And Aims: Overweight and obesity are modifiable risk factors for atherosclerotic cardiovascular disease (ASCVD) in the general population, but their prevalence in individuals with heterozygous familial hypercholesterolaemia (HeFH) and whether they confer additional risk of ASCVD independent of LDL cholesterol (LDL-C) remains unclear.
Methods: Cross-sectional analysis was conducted in 35 540 patients with HeFH across 50 countries, in the EAS FH Studies Collaboration registry. Prevalence of World Health Organization-defined body mass index categories was investigated in adults (n = 29 265) and children/adolescents (n = 6275); and their association with prevalent ASCVD.

Methamphetamine (METH), a synthetic stimulant, has seen an escalating abuse situation globally over the past decade. Although the molecular mechanism underlying METH-induced neurotoxicity has been explored, the dysfunction of brain-derived neurotrophic factor (BDNF) neuroprotection in the context of METH neurotoxicity remains insufficiently understood. Our previous studies have found that METH induced neurotoxicity and BDNF expression in rat primary neurons, necessitating further research into this paradox.

Electronic address:
Rhabdomyosarcoma (RMS), the most common pediatric soft tissue sarcoma, arises in skeletal muscle and remains in an undifferentiated state due to transcriptional and post-transcriptional regulators. Among its subtypes, fusion-negative RMS (FN-RMS) accounts for the majority of diagnoses in the pediatric population. MicroRNAs (miRNAs) are non-coding RNAs that modulate cell identity via post-transcriptional regulation of messenger RNAs (mRNAs).
