Immobilization-related skeletal muscle atrophy is a major concern to patients in Intensive Care Units and it has a profound effect on the quality of life. However, the underlying molecular events for the therapeutic effect of electroacupuncture to treat muscle atrophy have not been fully elucidated. Here we developed an immobilization mouse model and tested the hypothesis that skeletal muscle weakness may be caused by the increased expression of γ and α7 nicotinic acetylcholine receptors (nAChRs) on muscle cell membranes, while electroacupuncture could decrease the expression of γ and α7 nicotinic acetylcholine receptors...

Estrogen deficiency following menopausal provokes alveolar bone loss, remodeling and inflammation. Eugenol is a phenolic compound with wide dental applications and anti-inflammatory properties. In the present study, the potential protective role of eugenol against alveolar bone deformities was investigated in an ovariectomized (OVX) rodent model. Two doses of eugenol (2.5 and 5 mg/kg/d) were administered to OVX animals for 12 weeks. In Serum, markers of bone metabolism and pro-inflammatory cytokines were estimated using ELISA...

Renal replacement lipomatosis (RRL) is a rare disorder which exhibits extensive proliferation of fatty tissue within the renal sinus, hilum, and perirenal region. The pathogenesis of this entity is unknown, though association with aging, renal atrophy, longstanding chronic urinary infections has been noted. Although imaging modalities may suggest the diagnosis of this entity, it is histopathology that clinches the diagnosis most accurately. We report a case of a 52 year old male who presented with nonfunctioning kidney and was histopathologically confirmed to be a case of renal replacement lipomatosis...

Intra and inter-cellular calcium signaling is present in all types of cells and body tissues. In the human brain, calcium currents and waves are related to mental activities, including emotions. We present a theoretical interpretation of these phenomena suggesting their involvement in chronic emotional patterns and in the pathology of cancer. Recent developments on biophysics, translational biology and psychoneuroendocrinoimmunology (PNEI) can support explanatory hypotheses about the link between emotional stresses and the origin and development of different types of tumor cells...

BACKGROUND: LMTM is being developed as a treatment for AD based on inhibition of tau aggregation. OBJECTIVES: To examine the efficacy of LMTM as monotherapy in non-randomized cohort analyses as modified primary outcomes in an 18-month Phase III trial in mild AD. METHODS: Mild AD patients (n = 800) were randomly assigned to 100 mg twice a day or 4 mg twice a day. Prior to unblinding, the Statistical Analysis Plan was revised to compare the 100 mg twice a day as monotherapy subgroup (n = 79) versus 4 mg twice a day as randomized (n = 396), and 4 mg twice a day as monotherapy (n = 76) versus 4 mg twice a day as add-on therapy (n = 297), with strong control of family-wise type I error...

We recently reported that alpha-2 macroglobulin (A2M) is a biomarker of neuronal injury in Alzheimer's disease (AD) and identified a network of nine genes co-expressed with A2M in the brain. This network includes the gene encoding SPARCL1, a protein implicated in synaptic maintenance. Here, we examine whether SPARCL1 is associated with longitudinal changes in brain structure and function in older individuals at risk for AD in the Baltimore Longitudinal Study of Aging. Using data from the Gene-Tissue Expression Project, we first identified two single nucleotide polymorphisms (SNPs), rs9998212 and rs7695558, associated with lower brain SPARCL1 gene expression...

Hemophilic arthropathy (HA) is one of the most common and typical manifestation in the course of recurrent bleeding episodes in patients with hemophilia. Clinical and subclinical joint bleeding episodes gradually lead to irreversible changes manifesting themselves as pain, progressing ankylosis, marked limitation of the range of motion, muscle atrophy and osteoporosis commonly concomitant with joint deformity resulting from chronic proliferative synovitis and both cartilage and bone degeneration leading to the final functional impairment of the joint...

We compared the retinal thickness in the unaffected eyes among the following subtypes of unilateral optic neuritis (ON): multiple sclerosis (MS-ON), neuromyelitis optica spectrum disorder with anti-AQP4 autoantibody (AQP4-ON), patients with serum anti-MOG antibody (MOG-ON), and idiopathic ON. In the chronic phase, macular GCC and circum-papillary RNFL in the unaffected eyes were both atrophied in MS-ON and AQP4-ON, but were not atrophied in the others. Titers of anti-AQP4-Ab was suggested to be associated with such latent neurodegenerative process in AQP4-ON...

BACKGROUND: In the chronic stages of moderate-severe traumatic brain injury (TBI), progressive hippocampal volume loss-continuing well after acute neurological insults have resolved-has now been well documented. Previous research in other populations suggests that elevated anxiety symptoms are associated with compromise to the medial temporal lobes. OBJECTIVE: To examine whether higher anxiety symptoms predict greater hippocampal volume loss in moderate-severe TBI...

Background: In chronic obstructive pulmonary disease (COPD), weakness and muscle mass loss of the quadriceps muscle has been demonstrated to predict survival and mortality rates of patients. Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK), as a member of the TNF superfamily, has recently been identified as a key regulator of skeletal muscle wasting and metabolic dysfunction. So our aim was to study the role of TWEAK during quadriceps muscle atrophy and fiber-type transformation in COPD model rats and its possible pathway...

Reduced muscle activity leads to muscle atrophy and function loss in patients and animal models. Satellite cells (SCs) are postnatal muscle stem cells that play a pivotal role in skeletal muscle regeneration following injury. The regenerative potential, satellite cell numbers, and markers during recovery following immobilization of the hindlimb for seven days were explored. In mice exposed to seven days of hindlimb immobilization, in those exposed to recovery (seven days, splint removal), and in contralateral control muscles, muscle precursor cells were isolated from all hindlimb muscles (fluorescence-activated cell sorting, FACS), and SCs and muscle regeneration were identified using immunofluorescence (gastrocnemius and soleus) and electron microscopy (EM, gastrocnemius)...

Among the soluble factors that regulate skeletal muscle function, Transforming Growth Factor type Beta 1 (TGF-b1) is one of the most studied. This factor inhibits myogenesis and regeneration by regulating the activity and function of satellite cells (SCs). Indeed, TGF-b has a central role in muscle pathologies in which there is development of fibrosis and/or atrophy of skeletal muscle. Thus, in this review we present the critical and recent antecedents regarding the mechanisms and cellular targets involved in the effects of TGF-b1 in the muscle, in pathological processes such as the inhibition of regeneration, fibrosis and atrophy...

Wieacker-Wolff syndrome is a rare congenital syndrome with few reported cases in the current literature. It is traditionally described in males as an X-linked recessive disorder associated with congenital contractures of the feet, progressive neurologic muscular atrophy, and intellectual delay caused by ZC4H2 mutations. The purpose of this paper is to present a female individual with a classic phenotype and cleft palate, a previously undescribed finding in this syndrome. Recent reports have demonstrated that females are rarely severely affected and phenotypic expression is difficult to predict [Zanzottera et al...
