In this study, the treatment of vegetable oil refinery plant condensate effluent (VORCE) having high total suspended solids (TSS) and chemical oxygen demand (COD) generated from acid oil unit was focused. The utilization of waste Brassica nigra meal (BNM) as protein flocculant in treating VORCE was explored. The B.

Proper knee kinematics depends upon the integrity of ACL at its femoral and medial tibial spine attachments. Tibial spine fractures disrupt this complex and if untreated can lead to pain, instability and functional limitation. So proper diagnosis and early treatment of tibial spine avulsion fracture is important.

Case: We report a case of melioidotic septic arthritis of the ankle and secondary osteomyelitis of the talus in a 64-year-old farmer with diabetes mellitus. Arthroscopic drainage and debridement, followed by 6 months of appropriate antibiotic therapy, resulted in a good short-term outcome.

Conclusion: Melioidotic septic arthritis of the ankle is extremely rare.

Introduction: Clinically, subcoracoid impingement is characterized by pain at the anterior aspect of the shoulder that is induced by adduction, internal rotation and forward flexion. This position leads to narrowing of the Coraco-Humeral Interval (CHI)-that is, the space between the coracoid process and the lesser tuberosity of the humerus. Structures in the rotator interval are at greatest risk for impingement which includes the Subscorapularis tendon, tendon of the long head of the biceps, and the middle gleno-humeral ligament.

Unlabelled: Dematiaceous fungi are the etiological agents of phaeohyphomycosis. Diverse presentations of infectious syndromes are seen, ranging from local infections after trauma to widely disseminated infection in immunocompromised patients. Fonsecaea pedrosoi species have been reported to cause an increasing number of infections, particularly in severely immunocompromised patients.

Unlabelled: Isolated midtarsal (Chopart's) joint dislocations are rare, although cases involving medial, lateral, plantar, and dorsal displacement have been reported. These dislocations are often associated with osteochondral fractures. To the best of our knowledge, isolated dorsal midtarsal dislocation owing to plantarflexion of the forefoot on the hindfoot with the ankle in a neutral or dorsiflexed position is rare.

Introduction: Angio-osteohypotrophic syndrome is also known as Servelle-Martorell angiodysplasia. It is characterized by venous or, rarely, arterial malformations, which may result in limb hypertrophy and bony hypoplasia. Extensive involvement of the upper limb is a rare feature of Servelle-Martorell syndrome.

Background: The importance of tumor free margins in outcome of cancer surgery is well known. Often the pathological margins are reported to be significantly smaller than the in situ margins. This discrepancy is due to margin shrinkage the quantum of which has not been studied in patients with oral cancers.

Substance P is released from nerve endings in the heart under pathological conditions like ischemia, but its action on cardiac cells has not been investigated. This study tested the hypothesis that substance P is mitogenic to adult cardiac fibroblasts and delineated the underlying mechanism(s). Substance P, acting via neurokinin-1 (NK-1) receptors, stimulated cellular hyperplasia over a range of 1-10 micromol/l.

Magnesium deficiency is known to produce myocardial fibrosis in different animal models, but the underlying mechanisms are unclear. However, circulating levels of pro-oxidant and mitogenic factors are reported to be elevated in a rodent model of acute magnesium deficiency, suggesting a role for humoral factors in the pathogenesis of the cardiovascular lesions. Probing the mechanism of cardiac fibrogenesis in magnesium deficiency, the present study furnished evidence that serum from magnesium-deficient rats has a more marked effect than serum from magnesium-sufficient rats on mitogenesis, net collagen production, and superoxide generation in cardiac fibroblasts from young adult rats.

Thirty-three patients with germ cell tumor of the ovary were seen at Kidwai Memorial Institute of Oncology (KMIO), Bangalore, between 1996 and 1999. Twelve patients had endodermal sinus tumor (EST), 11 dysgerminoma, seven mixed germ cell tumor, and three immature teratoma. Thirteen patients had bulky residual disease of >10 cm after the primary surgery.

Since the recognition of the importance of calcium ions to cardiac contractility, the effects of alterations in calcium homeostasis on cardiac myocyte function have attracted immense attention. However, the possibility that changes in extracellular calcium concentration or the administration of calcium channel blockers may exert significant effects on cardiac fibroblasts has not hitherto been explored. This communication presents evidence, for the first time, that EGTA, calcium-free incubation and L-type calcium channel blockers increase endogenous superoxide production in adult rat cardiac fibroblasts.

Serum samples from 43 cases of Guillain-Barré Syndrome (GBS), 32 non-GBS neurology patients, and 35 healthy persons from a medical institute in Kerala, India, were tested for antibody levels against a Campylobacter jejuni strain Penner serotype 0:19 by agglutination and ELISA. Twenty-six percent of samples from GBS cases showed high antibody levels in all assays. Of 8 stool samples of new GBS cases examined by culture, 38% were positive for C.
