Abstract
Several methods are used to evaluate the inflammatory changes. Measurement of edema is the most commonly used method for evaluating artificially induced inflammation in rat model. In this context, we present a method for the measurement of volume of rat paw, in which two glass columns containing fluid are connected by a glass tube. Paw is immersed in one column and the other column is placed on weighing balance. Upon immersion of paw, equal volume of fluid displaced applies a force F, which shows specific and proportional increment in the level of fluid in both the columns, which could then be detected by weighing balance, as 'Force = Weight' of displaced fluid, using the specific gravity of the fluid and the volume of paw, and thus the change in the volume of paw can be calculated. The rat paw immersed in column without touching the wall of the column facilitates the accurate measurement of volume of paw when measured several times. Present method is validated for its accuracy and reproducibility when internal radii of both the columns were same or different. Presented method is also cost-effective and hence can be used for the academic and the commercial animal research purpose, without compromising the precision of the evaluation.

Abstract
A schwannoma is a benign, encapsulated tumour that is derived from neural sheath (Schwann) cells. Approximately 25-40% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck; oropharyngeal occurrence is extremely rare. Among the various histological types of schwannomas reported to date, the ancient (degenerative) variant is the most rare. To our knowledge, this is the first report of an ancient schwannoma in the parapharynx with an extensive oropharyngeal component causing dysphagia. Dysphagia was the prominent symptom because of the location and volume of the lesion. The tumour was excised via a transcervical approach.

Abstract
The cow and its milk have been held sacred in the world since the dawn of human civilization. Indian ancient Vedic texts describe the virtues of milk and dairy products, as is authenticated by modern scientific principles and proofs. Therefore, milk has been considered as one of the most natural and highly nutritive part of a daily balanced diet. Currently, the integration of advanced scientific knowledge with traditional information is gaining incredible momentum toward developing the concept of potential therapeutic foods. Furthermore, new advances toward understanding the therapeutic roles of milk and milk products have also given a new impetus for unraveling the age old secrets of milk. At present, the best-known examples of therapeutic foods are fermented milk products containing health promoting probiotic bacteria. In the present article, we have tried to review the various aspects of the therapeutic nature of milk and fermented dairy products in a highly up-dated manner, and offer an in-depth insight into the development of targeted therapeutic future foods as per the requirements of consumers.

Abstract
Men who have sex with men (MSM) in India are a core risk group for HIV. Heavy alcohol consumption is associated with increased sexual risk-taking behaviours in many cultures, in particular among MSM. However, no studies to date have explored alcohol use and HIV risk among MSM in India. MSM in Chennai, India (n = 210) completed an interviewer-administered behavioural and psychosocial assessment. Bivariate and multivariable logistic regression procedures examined behavioural and demographic associations with weekly alcohol consumption. Twenty-eight percent of the sample (n = 58) reported using alcohol at least weekly to the point of being buzzed/intoxicated, which was associated with older age, being married to a woman, being panthi (masculine appearing, predominantly insertive partners) versus kothi (feminine acting/appearing and predominantly receptive partners), weekly tobacco use, unprotected anal sex and unprotected vaginal sex in the three months prior to study enrollment (all P < 0.05). In a multivariable model, unprotected vaginal sex in the previous three months and being married to a women were unique variables associated with weekly alcohol use (all P < 0.01). Further investigation of alcohol use within the context of sexual risk taking is warranted among Indian MSM. Panthis and MSM who are married to women may be particularly likely to benefit from interventions to decrease alcohol intake and concurrent unsafe sex.

Abstract
BACKGROUND Rigid internal fixation with metals is a reliable method of achieving osteosynthesis while allowing the patient passive or even functional loading of the fracture or osteotomised bone segments. The disadvantages with metals have led to the introduction of resorbable polymers in rigid internal fixation. METHODS This study was conducted to evaluate the efficacy of these polymers as compared to titanium in fixation of bone segments fixation in 40 patients of zygomatic complex fractures and craniosynostosis management. The cases were followed up for one year. RESULT The stability of the fixation was found to be comparable to metallic fixation though the armamentarium and procedure of fixation of resorbable system was more demanding and the technique sensitive. CONCLUSION The resorbable system is a good system for rigid internal fixation in specific conditions where muscular and stress forces are not a determining factor in fragment displacement.

Abstract
Microarray studies have been performed on lung tissue, freshly isolated circulating cells and cells cultured from patients with idiopathic, hereditary and secondary forms of pulmonary arterial hypertension (PAH). These studies have provided a wealth of information on the characteristics of end-stage disease, but information about the origin of disease is only clear in hindsight. The central conclusions that can be drawn from these studies are that end-stage disease includes a massive but currently poorly defined inflammatory response, induction of angiogenesis genes for an as yet remaining unknown purpose, suppression of the BMP pathway even in idiopathic and secondary cases, and a host of more subtle changes, including mitochondrial and actin organisation changes. Moreover, the same physiologic endpoints can be achieved through use of any of multiple genes, and so specific genes are usually less important than the pathways they lie in; the exception to this rule must lie in as yet undefined critical nodes. Finally, the lack of consistency in methodologies of analysis makes cross-experiment comparisons difficult, and likely means that there is data collected in these studies that await interpretation.

Abstract
PURPOSE Brain abscesses often present an aetiological dilemma. Microscopy is insensitive and culture techniques are time consuming. Hence, a new rapid technique in vitro Proton Magnetic Resonance Spectroscopy (1HMRS) was evaluated for its usefulness in the identification of aetiology of brain abscesses. MATERIALS AND METHODS A total of 39 pus specimens from brain abscesses were subjected to in vitro 1HMRS. These pus specimens were also processed by conventional culture methods. The spectral patterns generated by in vitro 1HMRS were further correlated with culture results. RESULTS Pus specimens which showed the presence of anaerobes on culture revealed the presence of multiplet at 0.9 ppm (100%), lactate-lipid at 1.3 ppm (100%), acetate at 1.92 ppm (100%) and succinate at 2.4 ppm (75%). Pus specimens that revealed the presence of facultative anaerobes on culture showed a pattern B, i.e., the presence of lactate-lipid at 1.3 ppm (100%), acetate at 1.92 ppm (88.88%) along with the multiplet at 0.9 ppm (100%). Pattern C was seen in aerobic infection which showed the presence of lactate-lipid at 1.3 ppm (100%) along with the multiplet at 0.9 ppm. Pus from two tuberculous abscesses showed the complete absence of multiplet at 0.9 ppm. CONCLUSIONS We observed in this study that it was possible to differentiate bacterial and tuberculous brain abscesses using in vitro 1HMRS. Further, it was also possible to distinguish between aerobic and anaerobic brain abscesses on the basis of spectral patterns. In vitro 1HMRS of fungal and actinomycotic brain abscess are also presented for its unusual spectra.

Abstract
Migraine is a neurological disorder that is associated with increased levels of calcitonin gene-related peptide (CGRP) in plasma. CGRP, being one of the mediators of neurogenic inflammation and a phenomenon implicated in the pathogenesis of migraine headache, is thus suggested to have an important role in migraine pathophysiology. Polymorphisms of the CALCA gene have been linked to Parkinson's disease, ovarian cancer and essential hypertension, suggesting a functional role for these polymorphisms. Given the strong evidence linking CGRP and migraine, it is hypothesised that polymorphisms in the CALCA gene may play a role in migraine pathogenesis. Seemingly non functional intronic polymorphisms are capable of disrupting normal RNA processing or introducing a splice site in the transcript. A 16bp deletion in the first intron of the CALCA gene has been reported to be a good match for the binding site for a transcription factor expressed strongly in neural crest derived cells, AP-2. This deletion also eliminates an intron splicing enhancer (ISE) that may potentially cause exon skipping. This study investigated the role of the 16bp intronic deletion in the CALCA gene in migraineurs and matched control individuals. Six hundred individuals were genotyped for the deletion by polymerase chain reaction followed by fragment analysis on the 3130 Genetic Analyser. The results of this study showed no significant association between the intronic 16bp deletion in the CALCA gene and migraine in the tested Australian Caucasian population. However, given the evidence linking CGRP and migraine, further investigation of variants with this gene may be warranted.

Abstract
Introduction: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) shares common symptoms with migraine. Most CADASIL causative mutations occur in exons 3 and 4 of the Notch 3 gene. This study investigated the role of C381T (rs 3815188) and G684A (rs 1043994) single nucleotide polymorphisms (SNP) in exons 3 and 4, respectively, of the Notch 3 gene in migraine. Results: The first part of the study, in a population of 275 migraineurs and 275 control individuals, found a significant association between the C381T variant and migraine, specifically in migraine without aura (MO) sufferers. The G684A variant was also found to be significantly associated with migraine, specifically in migraine with aura (MA) sufferers. A follow-up study in 300 migraineurs and 300 control individuals did not show replicated association of the C381T variant with migraineurs. However, the G684A variant was again shown to be significantly associated with migraine, specifically with MA. Conclusion: Further investigation of the G684A variant and the Notch 3 gene is warranted to understand their role in migraine.
