Unlocking the Potential of Machine Learning in Co-crystal Prediction by a Novel Approach Integrating Molecular Thermodynamics.

Co-crystal engineering is of interest for many applications in pharmaceutical, chemistry and material fields, but rational design of co-crystals is still challenging. Although artificial intelligence has brought major changes in the decision-making process for materials design, yet limitations in generalization and mechanistic understanding remain. Herein, we sought to improve prediction of co-crystal by combining mechanistic thermodynamic modeling with machine learning.

MicroRNA-203 inhibits proliferation and invasion, and promotes apoptosis of osteosarcoma cells by targeting Runt-related transcription factor 2.

Accumulating evidence indicates that microRNA-203 (miR-203) is abnormally expressed in many human tumor tissues and significantly associated with the occurrence, development and clinical outcomes of human tumors. The aim of this study was to determine the target genes and functional significance of miR-203 in osteosarcoma cells. We found reduced expression of miR-203 in osteosarcoma tissues and cells (MG63 and U2-OS) compared with the adjacent normal tissues and normal osteoblastic cells (hFOB1.

Roles of Cell Cyle Regulators Cyclin D1, CDK4, and p53 in Knee Osteoarthritis.

Objective: The aim of this study was to investigate the roles of cyclin D1, CDK4, and p53 in knee osteoarthritis (KOA).

Methods: A total of 76 healthy controls and 154 KOA cases (grades ranging from II to IV) were recruited. Protein expression of cyclin D1, CDK4, and p53 were detected by immunohistochemistry, and mRNA expression levels of the cyclin D1, the CDK4, and the p53 genes were measured by reverse transcription-polymerase chain reaction.

Association of the A23G polymorphism with the risk of head and neck carcinomas: Evidence from 5,491 subjects.

The gene participates in modulating DNA damage recognition during the DNA nucleotide excision repair process. Current data regarding the association of the A23G polymorphism with the risk of head and neck squamous cell carcinoma (HNSCC) remain controversial, and meta-analyses focusing on the HNSCC risk and this polymorphism are limited. Therefore, the aim of the present study was to derive a more precise estimation of this association by a meta-analysis of all the eligible studies.

Papillary squamous cell carcinoma of the oral mucosa: a clinicopathologic and immunohistochemical study of 12 cases and literature review.

Papillary squamous cell carcinoma (SCC) (PSCC) of the oral mucosa is a relatively rare but distinct variant of SCC of head and neck. The objectives of this study were to describe the clinicopathologic and immunohistochemical features of a series of patients with oral PSCC and to review the literature on this topic. Retrospective review of patients with clinical and pathologic diagnosis of PSCC (n = 12) between 2000 and 2008 in our institution was conducted.

A clinicopathological study on verrucous hyperplasia and verrucous carcinoma of the oral mucosa.

Background: Oral verrucous hyperplasia (VH) and verrucous carcinoma (VC) are two clinicopathologically distinctive oral verrucous lesions. The objective of this study was to investigate the clinicopathological features of the two verrucous lesions and estimate their relationship from China.

Methods: Retrospective review of two series of patients with histologically confirmed VH (n = 121) and VC (n = 56) between 1996 and 2009 in our hospital were conducted.
