Different weight ratios of alginate/gum arabic (GA) solutions were prepared to serve as the wall material of liquid-core hydrogel beads (LHB) that were formulated to protect the total phenolic compounds (TP) of radish by-product juice from degradation during storage and release in simulated gastrointestinal fluid. The diameter of LHB ranged from 4.63 to 5.66mm with a sphericity lower than 0.05. LHB formulated with 25% GA (AGB0.25) exhibited the highest hardness (26.63N), and those formulated with 50% GA (AGB0...

INTRODUCTION: Massive rotator cuff tears (RCTs) in the context of shoulder dislocations are relatively uncommon in the young adult (<40 years) and if reported are more commonly described in association with acute traumatic anterior glenohumeral dislocations. They have rarely been described with posterior dislocations, regardless of patient age. This is the 1(st) case reported in the context of posterior dislocations, where a triad of biceps tendon rupture, posterior dislocation, and RCTs was observed during surgery...

BACKGROUND: Pathologies of the long head of biceps tendon (LHB) can cause anterior shoulder pain. Surgical treatment includes tenotomy and tenodesis (TD), however TD causes fewer cosmetic deformities and less cramping of the biceps muscle. To date, numerous techniques for TD have been described but the "gold standard" has not yet been established. OBJECTIVES: The purpose of this study is to evaluate the functional and cosmetic outcome following subpectoral biceps TD with an interference screw and a cortical-button (STLHB-IC) after 1 year...

The LHb expression is up-regulated during puberty in female zebrafish. However, the molecular mechanism underlying how LHb expression is regulated during puberty remains largely unknown. In this study, we found that the mRNA expression levels of lhb, fshb and cyp19a1b were up-regulated along with the puberty onset in zebrafish. Among the three nuclear estrogen receptors (nERs), the esr2b is the only type whose expression is significantly up-regulated during puberty onset in the pituitary. However, in situ hybridization results revealed that lhb mRNA was colocalized with esr1 and esr2a but not esr2b...

Depending on the stage of gonad maturation, as well as other factors, gonadal steroids can exert either a positive or negative feedback at the brain and pituitary level. While this has been demonstrated in many teleost species, little is known about the nature of steroid feedback in Gadiform fish. Using an optimized in vitro model system of the Atlantic cod pituitary, the present study investigated potential effects of two physiologically relevant doses of estradiol, testosterone or dihydrotestosterone (DHT) on cell viability and gene expression of gonadotropin subunits (fshb/lhb) and two suggested reproduction relevant gonadotropin-releasing hormone receptors (gnrhr1b/gnrhr2a) during three stages of sexual maturity...

Animal including human behavior is highly sophisticated. Besides reflective actions it is largely based on the desire for magnificent internal feelings, which are provided by the reward system. Its counterpart an "anti-reward" system is mainly composed of the lateral habenular complex (LHb) and its extensive interconnections with the monoaminergic cell groups in the mid- and hindbrain. The present review focuses on the neuronal composition and the internal signaling in the LHb. Morphologically six distinct types of neurons (spherical, fusiform-1, fusiform-2, polymorphic, vertical, neurogliaform) can be identified...

Cadmium is an endocrine disruptor, impairing male reproduction. The objective of this study is to investigate whether cadmium affects rat Leydig cell regeneration and to dissect the underlying mechanism. Adult male Sprague-Dawley rats received a single intraperitoneal injection (i.p.) of 0, 0.5 or 1.0 mg/kg of cadmium chloride, followed by ethane dimethane sulfonate (EDS) treatment to eliminate adult Leydig cells 20 days later. Compared to control (0 dose), cadmium treatment reduced serum testosterone levels by days 21, 35, and 56 after EDS treatment...

There are several methods for long head of the biceps (LHB) tenodesis, yet the optimal option is still debatable. Here we introduce a technique for arthroscopic suprapectoral biceps tenodesis with an all-suture anchor, the transtendinous biceps tenodesis technique. The LHB tenodesis is performed by using the Y-Knot anchor (1.3-mm). A standard suprapectoral approach is used for the tenodesis. A 1.3-mm drill bit is used to drill through the midportion of the biceps tendon and underlying bone to make a pilot hole...

Previous studies have demonstrated that somatosensory stimuli influence dopamine transmission in the mesolimbic reward system and can reduce drug-induced motor behaviors, craving and dependence. Until now, the central links between somatosensory and brain reward systems are not known. Here, we show that the dorsal column (DC) somatosensory pathway contains projections that convey an inhibitory input from the periphery to mesolimbic reward circuits. Stimulation of the ulnar nerve under HT7 acupoint suppressed psychomotor response to cocaine, which was abolished by disruption of the DC pathway, but not the spinothalamic tract (STT)...

Abnormal potentiation in the lateral habenula (LHb) has been suggested to mediate depression-like behaviors. However, the underlying mechanisms of the synaptic efficacy regulation of LHb synapses and the potential for their modulation are only poorly understood. Here, we report that long-term synaptic depression (LTD) occurs in the LHb upon both low-frequency stimulation (LFS) and moderate-frequency stimulation (MFS). LFS-induced LTD (LFS-LTD) is accompanied by a reduction in presynaptic release probability, which is endocannabinoid (eCB) signaling dependent...

The evolutionarily conserved lateral habenula (LHb) enables dynamic responses to continually changing contexts and environmental conditions. A model is proposed to account for greater mnemonic and contextual control over LHb-mediated response flexibility as vertebrate brains became more complex. The medial prefrontal cortex (mPFC) provides instructions for context-specific responses to LHb, which assesses the extent to which this response information matches the motivation or internal state of the individual...

The suprachiasmatic nucleus (SCN) times the daily rhythms of behavioral processes including feeding. Beyond the SCN, the hypothalamic arcuate nucleus (ARC), involved in feeding regulation and metabolism, and the epithalamic lateral habenula (LHb), implicated in reward processing, show circadian rhythmic activity. These brain oscillators are functionally coupled to coordinate the daily rhythm of food intake. In rats, a free choice high-fat high-sugar (fcHFHS) diet leads to a rapid increase of calorie intake and body weight gain...

Jorge Mendoza
The main circadian clock in mammals is located in the hypothalamic suprachiasmatic nucleus (SCN), however, central timing mechanisms are also present in other brain structures beyond the SCN. The lateral habenula (LHb), known for its important role in the regulation of the monoaminergic system, contains such a circadian clock whose molecular and cellular mechanisms as well as functional role are not well known. However, since monoaminergic systems show circadian activity, it is possible that the LHb-clock's role is to modulate the rhythmic activity of the dopamine, serotonin and norephinephrine systems, and associated behaviors...

The recognition and binding of viral envelope protein to pediatric receptor subverts the membrane-trafficking apparatus to mediate virion export in young children. Here, we described a successful computational design of peptide ligands to target the intermolecular interaction between the virus large envelope protein (LHB) and adaptin receptor (ADT). Based on the crystal structure of ADT in complex with an oligopeptide segment corresponding to the core binding site of LHB, a sequence-specific amino acid preference profile was determined systematically for the ADT-binding peptides using structural bioinformatics approach...

The lateral habenula (LHb) has an important role in the behavioural response to salient, usually aversive, events. We previously demonstrated that activation of neurons in the LHb increases brown adipose tissue (BAT) thermogenesis and constricts the cutaneous vascular bed, indicating that the LHb contributes to the central control of sympathetic outflow to thermoregulatory effector organs. We have now investigated whether the LHb mediates BAT thermogenesis elicited by emotional stress, and whether the LHb modulates thermoregulatory sympathetic outflow via the rostral medullary raphé, a key integrative lower brainstem sympathetic control centre...

We tested the effectiveness of a novel 13-bp hepatitis B virus (HBV)-derived cis-acting element (CAE) (ACCTCGACAAGGC), called the DT2 CAE, in augmenting transgene expression delivered by plasmid vectors in eukaryotic cells. The addition of the DT2 CAE just upstream of the start codon of several different target proteins (luciferase, EGFP, LHB, HBsAg, and MIF) in DNA plasmid constructs enhanced their translation in a posttranscriptional manner, irrespective of cell type (cell lines or primary cells) or promoter (CMV or HBV preS1 promoters), suggesting its feasibility for enhanced protein production in eukaryotic cell systems...

Alcohol use disorder (AUD) or alcoholism is a chronic relapsing disorder. Our knowledge of alcoholism hinges on our understanding of its effects on the brain. This review will center on the effects of alcohol in the lateral habenula (LHb), an epithalamic structure that connects the forebrain with the midbrain and encodes aversive signaling. Like many addictive drugs, alcohol has both rewarding and aversive properties. While alcohol's euphoric property is believed to be important for the initiation of drinking, increasing evidence suggests that alcohol's negative affect plays a critical role in excessive drinking and alcohol dependence...
