N-β-alanyl-dopamine synthetase gene (ebony) regulates pigmentation and reproduction in the melon fly, Zeugodacus cucurbitae.

Background: The melon fly, Zeugodacus cucurbitae (Coquillett), is a significant pest of fruit and vegetable crops. In the physiological processes of insects, N-β-phenylalanine dopamine synthase (ebony) plays a crucial role in insect physiology, with its activity depending on the interaction between dopamine and β-alanine. However, our understanding of ebony's specific biological functions of in melon flies remains limited.

Rapid cold hardening and cold acclimation promote cold tolerance of oriental fruit fly, (Hendel) by physiological substances transformation and cryoprotectants accumulation.

Insect response to cold stress is often associated with adaptive strategies and chemical variation. However, low-temperature domestication to promote the cold tolerance potential of and transformation of main internal substances are not clear. Here, we use a series of low-temperature exposure experiments, supercooling point (SCP) measurement, physiological substances and cryoprotectants detection to reveal that pre-cooling with milder low temperatures (5 and 10°C) for several hours (rapid cold hardening) and days (cold acclimation) can dramatically improve the survival rate of adults and pupae under an extremely low temperature (-6.

MALAT1/miR-320a in bone marrow mesenchymal stem cells function may shed light on mechanisms underlying osteoporosis.

Introduction: Growing evidence supports the involvement of long noncoding RNAs (lncRNAs) in bone metabolism and diseases. This study aims to investigate the involvement of the lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in the pathological process of osteoporosis and the effects of MALAT1 on regulation of BMSC differentiation through competitive endogenous RNA (ceRNA) mechanisms.

Material And Methods: The expression of MALAT1 and miR-320a was determined using RT-PCR in bone tissue derived from female SD (Sprague Dawley) rats with osteoporosis.

Distraction Osteogenesis of Fibula Graft for Mandibular Reconstruction Following Ameloblastoma Ablation.

Background: Resection of maxillofacial may cause a series of complications such as loss of facial deformity, dysfunction, and psychological distress. Mandibular reconstruction following resection still remains difficult.

Methods: A 18-year-old male patient with mandibular ameloblastoma was admitted in the hospital of stomatology.

Different bone sites-specific response to diabetes rat models: Bone density, histology and microarchitecture.

Background And Purpose: Diabetes mellitus (DM) is the most common metabolic disorder that is characterized by hyperglycemia, it can be categorized by T1DM and T2DM. T1DM is also reported to cause bone loss. However, most reports regarding this aspect of T1DM have only investigated a single site; a comparison of bone loss from different areas of the body is still lacking.
