Apprehensions and emerging solutions in ML-based protein structure prediction.

The three-dimensional structure of proteins determines their function in vital biological processes. Thus, when the structure is known, the molecular mechanism of protein function can be understood in more detail and obtained information utilized in biotechnological, diagnostics, and therapeutic applications. Over the past five years, machine learning (ML)-based modeling has pushed protein structure prediction to the next level with AlphaFold in the front line, predicting the structure for hundreds of millions of proteins.

Impact of pretreatment body mass index on the survival of head and neck cancer patients.

Background: Differences in pretreatment body mass index (BMI) have been associated with survival in squamous cell carcinoma of head and neck (SCCHN). We examined effects of BMI on survival in SCCHN patients after stratifying patients by tumor human papillomavirus (HPV) status and subsite.

Methods: Totally 2204 SCCHN patients in a prospective study were included in this secondary analysis.

Establishing Normative Values for Healthy Term Infant Feeding Performance: Neonatal Eating Assessment Tool-Mixed, Oral Feeding Scale, and Early Feeding Skills Assessment.

Purpose: Infants with perceived feeding problems are frequently referred for assessment of their feeding abilities. However, little is known regarding how healthy nondysphagic infants perform on commonly used assessments, making determination of impairment difficult. The aim of this investigation was to elucidate the characteristics of healthy term infant feeding performance using three commonly employed clinical assessments: Neonatal Eating Assessment Tool-Mixed (NeoEat-Mixed), Oral Feeding Scale, and Early Feeding Skills (EFS).

Joint effect of human papillomavirus exposure, smoking and alcohol on risk of oral squamous cell carcinoma.

Background: Smoking, alcohol consumption, and human papillomavirus (HPV) infection are known risk factors for oral squamous cell carcinoma (OSCC) including SCC of oropharynx (SCCOP) and SCC of oral cavity (SCCOC). Researchers have examined each of these risk factors independently, but few have observed the potential risk of their interaction. This study investigated the interactions among these risk factors and risk of OSCC.

Characterization of the oral microbiota among middle-aged men with and without human papillomavirus infection.

Objectives: To characterize the oral microbiota among middle-aged men and identify differences between men with a prevalent oral high-risk (oncogenic) HPV infection and those without.

Materials And Methods: This was a case-control study nested within a prospective screening study for HPV-related cancers among middle-aged men. 16S rRNA sequencing was used to characterize the oral microbiota and the cobas HPV Test was used to detect presence of oral high-risk HPV types.
