Functional outcome of arthroscopic reconstruction of anterior cruciate ligament tear using peroneus longus tendon autograft

Background: The objective of the study was to evaluate the functional outcome of arthroscopic reconstruction of ACL tear using triple layered PLT autograft and to study its effect on ankle stability.Methods: The study included 25 patients. The range of age was 18-42 years. Pre-op clinical tests and MRI was done to confirm tear. Reconstruction was done arthroscopically. Physiotheraphy protocol was fixed for all patients. Final outcome was assessed at 6 months using IKDC score and ankle stability was assessed by grading muscle power (MRC grading) with the normal side as control.Results: IKDC score was normal or near normal in 21 patients and only 4 patients were rated as abnormal or severely abnormal. Mean IKDC Score was 83.53. Stability of the ACL was assessed using the Lachman test: normal in 18 cases (72%), 1+ laxity in 5 cases (20%), 2+ and 3+ in 1 case (4%) each. Pivot shift was negative in 15 cases (60%), Pivot glide was seen in 9 cases (36%) and gross pivot shift was seen in 1 patient. Partial meniscectomy of the medial meniscus was performed in 5 patients. No patient experienced ankle dysfunction however 2 patients had pressure pain in the region of the graft harvest.Conclusions: PLT graft is similar to the native ACL both in terms of thickness and strength. It can be an appropriate autograft option for ACL reconstruction without compromising ankle function and avoiding potential complications of hamstring and BPTB autograft obtained from the knee region

Idiopathic clubfoot treated by Ponseti method: a series of 300 cases

Background: Clubfoot is a complicated deformity of the foot. It is one of the commonest congenital deformities in children. The main aim of this study was to evaluate the efficacy management of clubfoot by Ponseti method.Methods: This prospective study included 300 children (456 club feet) below the age of 2 years with idiopathic clubfeet from January 2013 to December 2017. In all the cases the Ponseti method was used for the management. The severity of the deformity was assessed with the help of the Pirani score and clinical evaluation of the foot was done.Results: Out of 300 patients 204 patients were male and 96 patients were female and 144 were unilateral clubfoot and 156 were bilateral cases of clubfoot. The mean number of casts required for correction was 5.4 (4–10). Out of 456 clubfeet 356 (78%) feet were required tenotomy. There was relapse seen in 36 (7.9%) feet which had to be managed with 2–3 serial manipulations and casting and these resolved. Excellent result found in our study in 92% cases, good results were found in 5% cases and poor results were found in 3% cases.Conclusions: Ponseti technique is a very useful and effective method of management of idiopathic clubfoot up to 2 year of age

Impact of coagulopathy in geriatric traumatic brain injury

Background: Traumatic brain injury (TBI) is the leading cause of death in trauma patients in various parts of the world including India. Coagulation cascade is affected in TBI.  The severity of coagulopathy correlates with degree of primary injuries thus affecting the prognosis of geriatric patients. Since the prognosis of isolated TBI can be a challenge to predict at times. AIM: we wanted to study the potential of international normalized ratio (INR) test, prothrombin test (PT), platelet count as a prognostic tool in isolated TBI. Methods: INR, PT, platelet count reflects the coagulation status. In most trauma cases, it is a routine test as well. We collected the INR, PT, platelet count value at admission of 200 isolated geriatric TBI cases over a period of three months. Then, patients were followed-up and their outcome at three months from admission is scored using Glasgow outcome scale (GOS). The relationship of INR, PT, platelet count with GOS was studied.Results: From our limited study, we found that INR of 1.52, PT 17 sec or more and platelet count less than 1.10 lac predicts poor prognosis in cases of isolated geriatric TBI.Conclusions: It is important to early diagnose and early manage the coagulation abnormalities in isolated geriatric head injury patients

Proximal femoral nail- outcome and complications: a prospective study of 125 cases of proximal femoral fractures

Background: Fractures of the proximal femur are relatively common injuries in adults and common source of morbidity and mortality among the elderly. Fractures of the proximal femur include trochantric and subtrochantric fractures. The present study was designed to evaluate and analyze the role of proximal femoral nail (PFN) in the treatment of proximal femoral fractures.Methods: It was a prospective study on 125 cases of proximal femoral fractures. The fractures were classified according to AO classification. Salvati and Wilson Score were used for functional assessment.Results: In this study at 6 months follow up, union was achieved in 123 cases, open reduction was performed in 11% of cases (14 cases). Technical and mechanical complications were noted in 21% cases (27 cases). Reoperation rate was 4% (Five cases). According to Salvati and Wilson scoring system excellent results were seen in 36% of cases (45 cases), good results in 46% cases (58 cases), fair result in 13% cases (16 cases) and poor results in 5% cases (6 cases). Conclusions: It is concluded from our study that proximal femoral nailing is an attractive and suitable implant for Proximal Femoral Fractures and its use in unstable intertrochantric fractures is very encouraging

Comparative shoot regeneration in diploid and amphidiploid Brassica species and their interspecific hybrids

Shoot regeneration response in interspecific hybrids of Brassica species were assessed in relation to the diploid pollen parents and amphidiploid female parents. Superior regeneration responses were observed in interspecific combinations of B. carinata and B. nigra (BBC), B. juncea and B. campestris (AAB), and B. napus and B. campestris (AAC). Though synthetic B. napus regenerated with a frequency less than that of the better regenerating parent (B. oleracea), higher regeneration response was observed in the hybrid between B. napus and B. campestris. Two triploid combinations of the genetic constitution ABC, one obtained by crossing synthetic B. napus with B. nigra and the other by crossing natural B. juncea with B. oleracea, showed low regeneration responses. The response improved substantially in a tetraploid of the constitution ABBC obtained by crossing B. juncea with B. carinata. Key words: Brassica, alloploids, shoot regeneration

Distribution of fatty acids during germination of soybean seeds

Gas chromatographic determination of the fatty acids in the seeds of soybean (Glycine max) showed mainly linoleic, oleic and palmitic acids with linoleic acid being the major component. Changes in the distribution of fatty acids were measured during germination in the cotyledons and roots. A decrease in palmitic and oleic acids was observed in the cotyledons from 6 to 12 days, while linoleic acid increased during the same period. In roots also, the major fatty acid was linoleic acid, while palmitic and linolenic acids were higher in roots in comparison with the cotyledons. During the 3-12 days of germination period, no major changes in the distribution pattern of fatty acids were observed in the roots. The possible significance of these changes is discussed

Optically selective coatings

The natural optical selectivity of a material exhibited in the form of its reflectance, transmittance, or emittance spectra can be modified and tailored to yield any desired profile by applying surface coatings in the form of multilayers of suitable materials, or composite materials having an appropriate graded composition. This paper reviews the modes of selectivity, design and modelling of some technologically important optically selective coatings

Development of insect-resistant transgenic cabbage plants expressing a synthetic cryIA(b) gene from Bacillus thuringiensis

A synthetic cryIA(b) gene coding for an insecticidal crystal protein of Bacillus thuringiensis (Bt) was transferred to cabbage cultivar 'Golden Acre' by co-cultivating hypocotyl explants with Agrobacterium tumefaciens. Transformed plants resistant to kanamycin were regenerated. Hybridization experiments demonstrated gene integration and mRNA expression. Immunoblot analysis revealed high-level expression of Bt toxin protein in the transgenic plants. The expression resulted in a significant insecticidal activity of transgenic cabbage plants against the larvae of diamondback moth (Plutella xylostella). The results also demonstrated that a synthetic gene based on monocot codon usage can be expressed in dicotyledonous plants for insect control

Isomorphs in model molecular liquids

Isomorphs are curves in the phase diagram along which a number of static and dynamic quantities are invariant in reduced units. A liquid has good isomorphs if and only if it is strongly correlating, i.e., the equilibrium virial/potential energy fluctuations are more than 90% correlated in the NVT ensemble. This paper generalizes isomorphs to liquids composed of rigid molecules and study the isomorphs of two systems of small rigid molecules, the asymmetric dumbbell model and the Lewis-Wahnstrom OTP model. In particular, for both systems we find that the isochoric heat capacity, the excess entropy, the reduced molecular center-of-mass self part of the intermediate scattering function, the reduced molecular center-of-mass radial distribution function to a good approximation are invariant along an isomorph. In agreement with theory, we also find that an instantaneous change of temperature and density from an equilibrated state point to another isomorphic state point leads to no relaxation. The isomorphs of the Lewis-Wahnstrom OTP model were found to be more approximative than those of the asymmetric dumbbell model, which is consistent with the OTP model being less strongly correlating. For both models we find "master isomorphs", i.e., isomorphs have identical shape in the virial/potential energy phase diagram.Comment: 20 page
