DOD-SSR: An Adaptive Seamless Phase II/III Design With Dose Optimization Decision and Sample Size Re-estimation.

The adoption of seamless Phase II/III designs has grown in popularity as a strategy to potentially accelerate the drug development. Making well-informed decisions regarding the drug's potential and addressing important clinical inquiries at the conclusion of the exploratory phase has become a critical step. In response to the increased emphasis on dose optimization, it becomes logical to integrate treatment arm/dose selections into Phase II and implement corresponding design adjustments.

Correlation Analysis Between Prognostic Nutritional Index Trajectory Categories and Radiotherapy-induced Severe Oral Mucositis in Head and Neck Cancer Patients Undergoing Radiotherapy.

Purpose: To establish the potential prognostic nutritional index (PNI) trajectory categories and examine the association between these PNI trajectory categories and severe radiotherapy-induced oral mucositis (RIOM).

Materials And Methods: This was a longitudinal retrospective observational study on 470 head and neck cancer inpatients who were to undergo radiotherapy from a grade-A tertiary hospital in Hunan Province between July 2022 and October 2023. The latent class growth model and growth mixed model were used to identify PNI trajectory categories.

Development and Validation of the Healthcare-Seeking Intention Questionnaire in Patients with Diabetic High-Risk Foot.

Objective: Timely screening and intervention can prevent the development of the diabetic foot. However, delayed visits to the clinic are common among diabetic foot patients. The study aimed to develop and validate a questionnaire to assess healthcare-seeking behavior among patients with diabetic high-risk foot.

OptoLacI: optogenetically engineered lactose operon repressor LacI responsive to light instead of IPTG.

Optogenetics' advancement has made light induction attractive for controlling biological processes due to its advantages of fine-tunability, reversibility, and low toxicity. The lactose operon induction system, commonly used in Escherichia coli, relies on the binding of lactose or isopropyl β-d-1-thiogalactopyranoside (IPTG) to the lactose repressor protein LacI, playing a pivotal role in controlling the lactose operon. Here, we harnessed the light-responsive light-oxygen-voltage 2 (LOV2) domain from Avena sativa phototropin 1 as a tool for light control and engineered LacI into two light-responsive variants, OptoLacIL and OptoLacID.

Perceptions and experience of rural older people in oral health management in China: a qualitative study.

Quantitative measurement of cell-surface displayed proteins based on split-GFP assembly.

Background: Microbial cell surface display technology allows immobilizing proteins on the cell surface by fusing them to anchoring motifs, thereby endowing the cells with diverse functionalities. However, the assessment of successful protein display and the quantification of displayed proteins remain challenging. The green fluorescent protein (GFP) can be split into two non-fluorescent fragments, while they spontaneously assemble and emit fluorescence when brought together through complementation.

DOD-Combo: Bayesian dose finding design in combination trials with meta-analytic-predictive prior.

Combination therapy, a treatment modality that involves multiple treatment agents, has become imperative for improving treatment effectiveness and addressing resistance in the field of oncology. However, determining the most effective dose for these combinations, particularly when dealing with intricate drug interactions and diverse toxicity patterns, presents a substantial challenge. This paper introduces a novel Bayesian se-finding esign for inatin therapies with information borrowing, named the DOD-Combo design.

Mucosal vaccine-induced cross-reactive CD8 T cells protect against SARS-CoV-2 XBB.1.5 respiratory tract infection.

A nasally delivered chimpanzee adenoviral-vectored severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine (ChAd-SARS-CoV-2-S) is currently used in India (iNCOVACC). Here, we update this vaccine by creating ChAd-SARS-CoV-2-BA.5-S, which encodes a prefusion-stabilized BA.

The Trajectory of Oral Mucositis in Head and Neck Cancer Patients Undergoing Radiotherapy and its Influencing Factors.

Background: Oral mucositis (OM) is a common and severe side effect of radiotherapy in head and neck cancer (HNC). The study aimed to investigate the longitudinal changes in OM and its influencing factors in patients with HNC during radiotherapy.

Methods: This was a retrospective longitudinal observational study.

BEATS: Bayesian hybrid design with flexible sample size adaptation for time-to-event endpoints.

As the roles of historical trials and real-world evidence in drug development have substantially increased, several approaches have been proposed to leverage external data and improve the design of clinical trials. While most of these approaches focus on methodology development for borrowing information during the analysis stage, there is a risk of inadequate or absent enrollment of concurrent control due to misspecification of heterogeneity from external data, which can result in unreliable estimates of treatment effect. In this study, we introduce a Bayesian hybrid design with flexible sample size adaptation (BEATS) that allows for adaptive borrowing of external data based on the level of heterogeneity to augment the control arm during both the design and interim analysis stages.

Flow cytometry-based high-throughput screening of synthetic peptides for palladium adsorption.

Conventionally, the measurement of metal ion adsorption capacity in biosorbent relies on expensive and time-consuming ICP-OES technique. Herein, a semi-quantitative method to measure Pd(II) adsorption capacity of single cells has been presented by analyzing side scatter (SSC) intensity in flow cytometry. Within the sensitive range and applicable conditions, excellent linearity correlation (R ranges from 0.

Isoflurane Conditioning-Induced Delayed Cerebral Ischemia Protection in Subarachnoid Hemorrhage-Role of Inducible Nitric Oxide Synthase.

Background Recent evidence implicates inflammation as a key driver in delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage (SAH). Inducible nitric oxide synthase (iNOS) is one of the known major mediators of inflammation. We previously showed that an inhalational anesthetic, isoflurane, provides strong protection against delayed cerebral ischemia after SAH.

Isoflurane Conditioning Provides Protection against Subarachnoid Hemorrhage Induced Delayed Cerebral Ischemia through NF-kB Inhibition.

Delayed cerebral ischemia (DCI) is the largest treatable cause of poor outcome after aneurysmal subarachnoid hemorrhage (SAH). Nuclear Factor Kappa-light-chain-enhancer of Activated B cells (NF-kB), a transcription factor known to function as a pivotal mediator of inflammation, is upregulated in SAH and is pathologically associated with vasospasm. We previously showed that a brief exposure to isoflurane, an inhalational anesthetic, provided multifaceted protection against DCI after SAH.

Oral health behavior and oral health service utilization among cancer patients in China: A multicenter cross-sectional study.

A Reduced Starch Level in Plants at Early Stages of Infection by Viruses Can Be Considered a Broad-Range Indicator of Virus Presence.

The diagnosis of virus infection can facilitate the effective control of plant viral diseases. To date, serological and molecular methods for the detection of virus infection have been widely used, but these methods have disadvantages if applied for broad-range and large-scale detection. Here, we investigated the effect of infection of several different plant RNA and DNA viruses such as cucumber mosaic virus (CMV), tobacco mosaic virus (TMV), potato virus X (PVX), potato virus Y (PVY) and apple geminivirus on starch content in leaves of .
