A model finding a new Richardson potential with different scales for confinement and asymptotic freedom, by fitting the properties of {\D}^{++} and {\Om}^{-}

Phenomenological Richardson potential has built in asymptotic freedom (AF in short) and confinement, with only one parameter \La in the potential. But it is known that the scales of AF and confinement are not the same. In the present work a relativistic mean field calculation for baryons is tried out with two parameters \La and \La^\prime for AF and confinement respectively .To test the two parameter potential we calculate the energies and the magnetic moments, of the triple u - quark system ({\D}^{++}) and the triple s - quark system ({\Om}^{-}) and found good values for \La=100 MeV and \La^\prime ~= 350 MeV. So we believe that the modified Richardson potential should have AF scale \La ~= 100 MeV and the confinement scale \La^\prime ~= 350 MeV.Comment: Accepted for publication in Nuclear Physics

"The fruits of independence": Satyajit Ray, Indian nationhood and the spectre of empire

Challenging the longstanding consensus that Satyajit Ray's work is largely free of ideological concerns and notable only for its humanistic richness, this article shows with reference to representations of British colonialism and Indian nationhood that Ray's films and stories are marked deeply and consistently by a distinctively Bengali variety of liberalism. Drawn from an ongoing biographical project, it commences with an overview of the nationalist milieu in which Ray grew up and emphasizes the preoccupation with colonialism and nationalism that marked his earliest unfilmed scripts. It then shows with case studies of Kanchanjangha (1962), Charulata (1964), First Class Kamra (First-Class Compartment, 1981), Pratidwandi (The Adversary, 1970), Shatranj ke Khilari (The Chess Players, 1977), Agantuk (The Stranger, 1991) and Robertsoner Ruby (Robertson's Ruby, 1992) how Ray's mature work continued to combine a strongly anti-colonial viewpoint with a shifting perspective on Indian nationhood and an unequivocal commitment to cultural cosmopolitanism. Analysing how Ray articulated his ideological positions through the quintessentially liberal device of complexly staged debates that were apparently free, but in fact closed by the scenarist/director on ideologically specific notes, this article concludes that Ray's reputation as an all-forgiving, ‘everybody-has-his-reasons’ humanist is based on simplistic or even tendentious readings of his work

Polypoid multifocal ileo-colonic amyloidoma masquerading malignancy - A rare case report

Amyloidosis is a group of disorders characterized by extracellular deposition of a proteinaceous homogenous eosinophilic hyaline substance known as amyloid. Congo red staining is a specific stain for amyloid which shows an apple-green birefringence on polarized microscopy. Amyloid deposition can be systemic or localized. Primary amyloidosis (also known as AL amyloidosis) is the most common form of amyloidosis characterized by generalized deposition of excess immunoglobulin light chains. It is associated with an underlying plasma cell dyscrasia and has the maximum gastrointestinal (GI) involvement. Secondary amyloidosis is characterized by deposition of acute-phase reactant - serum amyloid A protein (also known as AA amyloidosis) and it is associated with infectious, inflammatory, or less commonly, neoplastic disorders. Renal dysfunction is the most common symptom of AA amyloidosis at diagnosis. Amyloidosis presenting as a localized mass is known as amyloidoma. Amyloidoma of the GI system is a rare finding in the absence of any systemic involvement. We report a rare case of localized multifocal polypoid amyloidoma in the lower GI tract, which masquerades as malignancy.&nbsp

The ultrasonic changes in maturing placenta in pregnancy complicated with hypertension and its correlation with neonatal outcome

Background: Hypertension is the most common medical problem encountered during pregnancy, complicating 2-3% of pregnancies. Obstetric ultrasound provides a cornerstone to other modalities used for assessing hypertensive disorders of pregnancy. This study was designed to detect the placental changes in hypertensive disorders of pregnancy and correlation with neonatal outcome.Methods: The study group comprised of 42 patients with pregnancy complicated with hypertension with period of gestation above 20 weeks and B.P. more than 140/90 mm of Hg measured on two occasions 6 hours or more apart. The control group consists of 42 normotensive patients matched with age and parity. One ultrasonic examination were performed between 28 weeks and 34 weeks and another after 34 weeks till term. Apart from routine parameters i.e. BPD, AC, FL, Amniotic fluid index, EBW and gestational age routine placental grading were performed according to the classification proposed by Grannum and associates. To evaluate perinatal outcome following measurement were studied – birth weight immediately after delivery, mode of delivery, perinatal morbidity and mortality , APGAR  score , presence of fetal distress.Results: In 97.62%  cases (41 out of 42 ) of control group showed Grade–II changes as opposed to 57.14% of cases (24 out of 42) in study group before 34 weeks.Conclusions: Accelerated maturation of placenta in pregnancy complicated with hypertension are more common in the hypertensive group

A study of brainstem auditory evoked responses in normal human subjects and normal variations as a function of stimulus and subject characteristics

Background: Brainstem auditory evoked responses (BAERs) are electrophysiological investigations have widespread clinical utility in neurology, audiology, neonatology and anesthesiology. BAER responses exhibit a normal variability due to various non-pathologic factors and age is one of the variables suggested to have considerable influence on normal BAE responses. Aging changes in the auditory system may significantly influence the interpretation of the auditory brainstem responses in comparison with younger adults. The present study was undertaken to study the different parameters of brainstem evoked responses in normal subjects and their variations with changing stimulus and subject characteristics among average Indian people.Methods: The test was conducted on 50 neuro-audiologically normal subjects (age-group of 5-60 years) selected from the OPD of ENT Department. Various audio-vestibular tests they were subjected to brainstem evoked response audiometry and responses were studied regarding various parameters of ABR details. An attempt was made to find out a normal range, normative values of various parameters and their variations with respect of their stimulus intensity and subject characteristics.Results: In the present study it was observed that absolute latencies of all waves decreased with increasing stimulus intensity. The mean absolute latency values of all waves were prolonged in male than those of female subjects. The mean inter-peak latency values of I-III, III-V and I-V were also prolonged in male. Effects of change in stimulus rate on absolute latencies of all waves were observed. There were increases in absolute latencies of all waves with increasing stimulus rate.Conclusions: Increased stimulus intensity caused decrease in latency values of all values. Wave V showed lesser degree of variation than the other components. Increase in stimulus rate caused increase in latency of all waves. Wave V showed lesser degree of variation than the other components. BERA can be performed with a wide range of stimulus variations. But what was clear in conclusion was that 60dB SL was the suitable intensity level. Also a wide variety of stimulus rate can be used in combination with either of the stimulus polarity. So any combination of stimulus intensity, rate and polarity may be used for clinical application of BERA. But essence is that there should be a prior adjustment of parameter norms according to subject and stimulus characteristics

Search for gravitational wave bursts in LIGO's third science run

We report on a search for gravitational wave bursts in data from the three LIGO interferometric detectors during their third science run. The search targets subsecond bursts in the frequency range 100-1100 Hz for which no waveform model is assumed, and has a sensitivity in terms of the root-sum-square (rss) strain amplitude of hrss ~ 10^{-20} / sqrt(Hz). No gravitational wave signals were detected in the 8 days of analyzed data.Comment: 12 pages, 6 figures. Amaldi-6 conference proceedings to be published in Classical and Quantum Gravit

Searching for a Stochastic Background of Gravitational Waves with LIGO

The Laser Interferometer Gravitational-wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to previous runs. Using data acquired during this science run, we place a limit on the amplitude of a stochastic background of gravitational waves. For a frequency independent spectrum, the new limit is $\Omega_{\rm GW} < 6.5 \times 10^{-5}$. This is currently the most sensitive result in the frequency range 51-150 Hz, with a factor of 13 improvement over the previous LIGO result. We discuss complementarity of the new result with other constraints on a stochastic background of gravitational waves, and we investigate implications of the new result for different models of this background.Comment: 37 pages, 16 figure

Adipocyte fetuin-A contributes to macrophage migration into adipose tissue and polarization of macrophages

Macrophage infiltration into adipose tissue during obesity and their phenotypic conversion from anti-inflammatory M2 to proinflammatory M1 subtype significantly contributes to develop a link between inflammation and insulin resistance; signaling molecule(s) for these events, however, remains poorly understood. We demonstrate here that excess lipid in the adipose tissue environment may trigger one such signal. Adipose tissue from obese diabetic db/db mice, high fat diet-fed mice, and obese diabetic patients showed significantly elevated fetuin-A (FetA) levels in respect to their controls; partially hepatectomized high fat diet mice did not show noticeable alteration, indicating adipose tissue to be the source of this alteration. In adipocytes, fatty acid induces FetA gene and protein expressions, resulting in its copious release. We found that FetA could act as a chemoattractant for macrophages. To simulate lipid-induced inflammatory conditions when proinflammatory adipose tissue and macrophages create a niche of an altered microenvironment, we set up a transculture system of macrophages and adipocytes; the addition of fatty acid to adipocytes released FetA into the medium, which polarized M2 macrophages to M1. This was further confirmed by direct FetA addition to macrophages. Taken together, lipid-induced FetA from adipocytes is an efficient chemokine for macrophage migration and polarization. These findings open a new dimension for understanding obesity-induced inflammation

Acute cholecystitis with massive upper gastrointestinal bleed: A case report and review of the literature

BACKGROUND: Cystic artery pseudoaneurysm is a rare complication following cholecystitis. Its presentation with upper gastrointestinal hemorrhage (UGIH) is even rarer. Thirteen patients with cystic artery pseudoaneurysm have been reported in the literature but only 2 of them presented with UGIH alone. CASE PRESENTATION: We report a 43-year-old woman who developed a cystic artery pseudoaneurysm following an episode of acute cholecystitis. She presented with haematemesis and melaena associated with postural symptoms. Upper gastrointestinal endoscopy revealed a duodenal ulcer with adherent clots in the first part of the duodenum. Ultrasonography detected gallstones and a pseudoaneurysm at the porta hepatis. Selective hepatic angiography showed two small pseudoaneurysms in relation to the cystic artery, which were selectively embolized. However, the patient developed abdominal signs suggestive of gangrene of the gall bladder and underwent an emergency laparotomy. Cholecystectomy with common bile duct exploration along with repair of the duodenal rent, and pyloric exclusion and gastrojejunostomy was done. CONCLUSION: This case illustrates the occurrence of a rare complication (pseudoaneurysm) following cholecystitis with an unusual presentation (UGIH). Cholecystectomy, ligation of the pseudoaneurysm and repair of the intestinal communication is an effective modality of treatment
