OBJECTIVE: Patients with substance use disorders (SUDs) exhibit low healthcare utilization despite high risk of poor outcomes. Telehealth expansion may boost utilization, but it is unclear whether telehealth can increase utilization for patients with SUDs beyond that expected for other chronic diseases amenable to remote treatment, like type 2 diabetes. This information is needed by health systems striving to improve SUD outcomes, specifically. This study compared the impact of telehealth expansion during the COVID-19 public health emergency (PHE) on utilization for patients with SUDs and diabetes...

G-ratio is crucial for understanding the nervous system's health and function as it measures the relative myelin thickness around an axon. However, manual measurement is biased and variable, emphasizing the need for an automated and standardized technique. Although deep learning holds promise, current implementations lack clinical relevance and generalizability. This study aimed to develop an automated pipeline for selecting nerve fibers and calculating relevant g-ratio using quality parameters in optical microscopy...

BACKGROUND: Recent studies have highlighted the role of low-grade systemic inflammation in linking periodontitis to cardiovascular disease (CVD) outcomes, but many aspects remain unclear. This study examines the independent and reciprocal associations of periodontitis and low-grade systemic inflammation with all-cause and CVD mortality in a large-scale cohort. METHODS: A total of 3047 participants from the prospective, population-based Study of Health in Pomerania (SHIP-START) were followed for a period of 13...

Simultaneous improvement for GY and GPC by using GWAS and GBLUP suggested a significant application in durum wheat breeding. Despite the importance of grain protein concentration (GPC) in determining wheat quality, its negative correlation with grain yield (GY) is still one of the major challenges for breeders. Here, a durum wheat panel of 200 genotypes was evaluated for GY, GPC, and their derived indices (GPD and GYD), under eight different agronomic conditions. The plant material was genotyped with the Illumina 25 k iSelect array, and a genome-wide association study was performed...

Spikelet number and grain number per spike are two crucial and correlated traits for grain yield in wheat. Photoperiod-1 (Ppd-1 ) is a key regulator of inflorescence architecture and spikelet formation in wheat. In this study, near-isogenic lines derived from the cross of a synthetic hexaploid wheat and commercial cultivars generated by double top-cross and two-phase selection were evaluated for the number of days to heading and other agronomic traits. The results showed that heading time segregation was conferred by a single incomplete dominant gene PPD-D1 , and the 2 kb insertion in the promoter region was responsible for the delay in heading...

OBJECTIVES: To characterize the incidence of stress urinary incontinence (SUI) after radical prostatectomy (RP), its treatment, and impact on quality of life (QoL) and work status 1 year after RP. MATERIALS/METHODS: Prostate cancer patients treated by RP (1998-2016) were selected from CaPSURE. SUI was defined as any pads per day (ppd) 1 year after RP. SUI procedures were tracked by CPT codes (sling and artificial sphincter). Patients reported work status (full-time, part-time, unpaid), UCLA PCa Index urinary function (UF) and bother (UB) and SF36 Index physical function (PF)...

Oxidase-mimicking nanozymes with specificity for catalyzing oxidation of aromatic amines are of great significance for recognition of aromatic amines but rarely reported. Herein, Cu-A nanozyme (synthesized with Cu2+ as a node and adenine as a linker) could specifically catalyze oxidation of o -phenylenediamine (OPD) in Britton-Robinson buffer solution. Such a specific catalytic performance was also corroborated with other aromatic amines, such as p -phenylenediamine (PPD), 1,5-naphthalene diamine (1,5-NDA), 1,8-naphthalene diamine (1,8-NDA), and 2-aminoanthracene (2-AA)...

PURPOSE: To compare laboratory markers of acute liver injury after transjugular intrahepatic portosystemic shunt (TIPS) creation performed using intravascular ultrasound (IVUS) guidance versus other techniques. MATERIALS AND METHODS: This single-center, retrospective study examined 293 TIPS performed between 2014 and 2022 (160 men; mean age 57.4, 71.7% for ascites, 158 with IVUS). Post-procedure day 1 (PPD 1) laboratory changes were classified by Common Terminology Criteria for Adverse Events (CTCAE) grade and were compared between IVUS and non-IVUS cases...

Para-phenylenediamine (PPD) is a derivative of benzene used as an ingredient in dyes, a photographic developing agent, and a component of engineered polymers. The carcinogenicity of PPD, which has been documented in several studies, may be related to its toxic effects on different compartments of the immune system. The main goal of this research was to evaluate the mechanism of the toxicity of PPD on human lymphocytes by exploiting the accelerated cytotoxicity mechanism screening (ACMS) technique. Lymphocytes were isolated from the blood of healthy persons using a Ficoll-Paque PLUS standard method...

We identified a large chromosomal deletion containing TaELF-B3 that confers early flowering in wheat. This allele has been preferred in recent wheat breeding in Japan to adapt to the environment. Heading at the appropriate time in each cultivation region can greatly contribute to stabilizing and maximizing yield. Vrn-1 and Ppd-1 are known as the major genes for vernalization requirement and photoperiod sensitivity in wheat. Genotype combinations of Vrn-1 and Ppd-1 can explain the variation in heading time. However, the genes that can explain the remaining variations in heading time are largely unknown...

Mutations in Photoperiod-1 (Ppd-1) gene are known to modify flowering time and yield in wheat. We cloned TaPpd-1 from wheat and found high similarity among the three homoeologs of TaPpd-1. To clarify the characteristics of TaPpd-1 homoeologs in different photoperiod conditions for inflorescence architecture and yield, we used CRISPR/Cas9 system to generate Tappd-1 mutant plants by simultaneous modification of the three homoeologs of wheat Ppd-1. Tappd-1 mutant plants showed no off-target mutations. Four T0 -edited lines under short-day length and three lines under long-day length conditions with the mutation frequency of 25% and 21%, respectively...

The timing of heading is largely affected by environmental conditions. In wheat, Vrn-1 and Ppd-1 have been identified as the major genes involved in vernalization requirement and photoperiod sensitivity, respectively. To compare the effects of Vrn-1 and Ppd-1 alleles on heading time under different environments, we genotyped Vrn-1 and Ppd-1 homoeologues and measured the heading time at Morioka, Tsukuba and Chikugo in Japan for two growing seasons. A total of 128 Japanese and six foreign varieties, classified into four populations based on the 519 genome-wide SNPs, were used for analysis...

BACKGROUND: Psoriasis is a common chronic inflammatory skin disease that often causes depression. Early life experience affects brain development and relates to depression. Whether the effect of different MS protocols in early life on anxiety-like and depressive-like behaviors in female offspring with imiquimod (IMQ)-induced psoriasis is unknown. METHODS: C57BL/6J mice were subjected to no separation (NMS), brief MS (15 min/day, MS15) or long MS (180 min/day, MS180) from postpartum days (PPD) 1 to PPD21...

BACKGROUND: The textile dye mix (TDM) 6.6% in petrolatum contains Disperse Blue (DB) 35, Disperse Yellow 3, Disperse Orange (DO) 1 and 3, Disperse Red 1 and 17, and DB 106 and 124. The most frequent allergen in TDM-positive patients is DO 3. Around 85% of para-phenylenediamine (PPD)-allergic dermatitis patients have been positive to DO 3. There has been a discussion to exclude DO 3 from TDM 6.6% because of strong simultaneous reactions to TDM and PPD. OBJECTIVES: To study if DO 3 can be excluded from TDM 6...

p -Phenylenediamine (PPD) has been classified as a strong skin allergen, but when it comes to toxicological concerns, benzoquinone diamine (BQDI), the primary oxidation derivative of PPD, is frequently considered and was shown to covalently bind nucleophilic residues on model peptides. However, tests in solution are far from providing a reliable model, as the cutaneous metabolism of PPD is not covered. We now report the synthesis of two 13 C substituted isotopomers of PPD, 1,4-(13 C) p -phenylenediamine 1 and 2,5-(13 C) p -phenylenediamine 2 , and the investigation of their reactivity in reconstructed human epidermis (RHE) using the high resolution magic angle spinning (HRMAS) NMR technique...

Despite its high potential, PD-L1 expressed by tumors has not been successfully utilized as a biomarker for estimating treatment responses to immunotherapy. Circulating tumor cells (CTCs) and tumor-derived exosomes that express PD-L1 can potentially be used as biomarkers; however, currently available assays lack clinically significant sensitivity and specificity. Here, a novel peptide-based capture surface is developed to effectively isolate PD-L1-expressing CTCs and exosomes from human blood. For the effective targeting of PD-L1, this study integrates peptide engineering strategies to enhance the binding strength and specificity of a β-hairpin peptide derived from PD-1 (pPD-1)...

INTRODUCTION: Studies have identified the presence of M1 and M2 macrophages (Mϕ) in injured intervertebral discs (IVDs). However, the origin and polarization-regulatory factor of M2 Mϕ are not fully understood. TGF-β is a regulatory factor for M2 polarization in several tissues. Here, we investigated the source of M2 Mϕ and the role of TGF-β on M2 polarization using a mice disc-puncture injury model. METHODS: To investigate the origin of M2 macrophages, 30 GFP chimeric mice were created by bone marrow transplantation...

PURPOSE: To compare the clinical and radiographic effectiveness of dental pulp stem cells (DPSCs) seeded onto L-PRF and L-PRF alone in the extraction socket of mandibular third molars. METHODS: This study analyzed 13 patients who required surgical removal of impacted bilateral mandibular third molars. The main outcome measures were the probing pocket depth (PPD) and clinical attachment levels (CAL) that were recorded for the adjacent second molars (LM2) at the baseline and 6 months after surgery...

Flowering is central to the transformation of plants from vegetative growth to reproductive growth. The circadian clock system enables plants to sense the changes in the external environment and to modify the growth and development process at an appropriate time. Photoperiod-1 ( Ppd-1 ), which is controlled by the output signal of the circadian clock, has played an important role in the wheat "Green Revolution." In the current study, we systematically studied the relationship between Ppd-1 haplotypes and both wheat yield- and quality-related traits, using genome-wide association analysis and transgenic strategies, and found that highly appropriate haplotypes had been selected in the wheat breeding programs...

Background. The present randomized clinical trial aimed to determine the additive clinical and microbiological benefits of diode laser (DL) with modified Widman flap (MWF) to manage chronic periodontitis. Methods. Seventy-two sites in 36 healthy non-smoking patients diagnosed with chronic periodontitis were randomly assigned to the test group (MWF + active DL) or control group (MWF + sham DL). Clinical (probing pocket depth [PPD], clinical attachment level [CAL]) and microbiological (colony-forming units [CFUs]) measurements were recorded at baseline and 6- and 6-month postoperative intervals...
