Purification of heparin binding oviduct specific proteins and its effect on in vitro embryo development in cattle

The objective of this study was to see the effect of purified heparin binding oviduct specific proteins (OSP) as media supplement on in vitro embryo developmental competence in cattle. The oviduct specific proteins were isolated from abattoir cattle oviducts and precipitated, dialyzed and at the end purified by high performance liquid chromatography system. The SDS-PAGE profile of eluted heparin binding protein (HBP) fraction showed bands between approximately 66-approximately 97 kDa, while heparin unbinding protein (HUBP) fraction showed two bands at approximately 66 kDa and in total protein (TP) bands were approximately 60-approximately 95 kDa. Collected all three OSP fractions were used as a media supplement in three different concentrations (0, 5 and 20 microg/mL) for in vitro maturation of immature oocytes, in vitro fertilization and culture of presumptive embryos at 38.5 degrees C in 5% CO2 incubator with maximum humidity. The highest cleavage rate (73.40 +/- 2.36%) was observed at 5 microg/mL concentration level and lowest cleavage rate (27.63 +/- 1.89%) was obtained in 20 microg/mL total protein (TP) fraction. The highest blastocyst formation (26.47 +/- 1.47%) also occurred in 5 microg/mL concentration of total protein (TP) fraction and the lowest blastocyst rate (3.60 +/- 1.80%) was achieved at 20 microg/mL HBP fraction. The highest cleavage rate in the control group was 60.45 +/- 2.66% in TP fraction and blastocyst formation was 11.66 +/- 2.54% in HUBP fraction which was not significantly differ from HBP fraction. These results indicate that at 5 microg/mL of total OSP fraction (TP) and HBP used as media supplement increased the cleavage rate significantly as compared to HUBP fraction, and total OSP fraction (TP) increased blastocyst formation significantly (P < 0.05) as compared to HBP & HUBP fraction.

Using FDG-PET to measure early treatment response in head and neck squamous cell carcinoma: quantifying intrinsic variability in order to understand treatment-induced change

BACKGROUND AND PURPOSE

Quantification of both baseline variability and intratreatment change is necessary to optimally incorporate functional imaging into adaptive therapy strategies for HNSCC. Our aim was to define the baseline variability of SUV on FDG-PET scans in patients with head and neck squamous cell carcinoma and to compare it with early treatment-induced SUV change.

MATERIALS AND METHODS

Patients with American Joint Committee on Cancer stages III-IV HNSCC were imaged with 2 baseline PET/CT scans and a third scan after 1-2 weeks of curative-intent chemoradiation. SUVmax and SUVmean were measured in the primary tumor and most metabolically active nodal metastasis. Repeatability was assessed with Bland-Altman plots. Mean percentage differences (%ΔSUV) in baseline SUVs were compared with intratreatment %ΔSUV. The repeatability coefficient for baseline %ΔSUV was compared with intratreatment %ΔSUV.

RESULTS

Seventeen patients had double-baseline imaging, and 15 of these patients also had intratreatment scans. Bland-Altman plots showed excellent baseline agreement for nodal metastases SUVmax and SUVmean, but not primary tumor SUVs. The mean baseline %ΔSUV was lowest for SUVmax in nodes (7.6% ± 5.2%) and highest for SUVmax in primary tumor (12.6% ± 9.2%). Corresponding mean intratreatment %ΔSUVmax was 14.5% ± 21.6% for nodes and 15.2% ± 22.4% for primary tumor. The calculated RC for baseline nodal SUVmax and SUVmean were 10% and 16%, respectively. The only patient with intratreatment %ΔSUV above these RCs was 1 of 2 patients with residual disease after CRT.

CONCLUSIONS

Baseline SUV variability for HNSCC is less than intratreatment change for SUV in nodal disease. Evaluation of early treatment response should be measured quantitatively in nodal disease rather than the primary tumor, and assessment of response should consider intrinsic baseline variability.

Primary disseminated extrapulmonary multidrug resistant tuberculosis

Disseminated tuberculosis is a common mode of presentation of tuberculosis in patients both with and without HIV/AIDS in India. However, primary multidrug resistance in disseminated tuberculosis involving only the extrapulmonary sites in an immunocompetent adult is rare. Here, we report a case of a 19-year-old man who had disseminated tuberculosis involving left pleura, pericardium, peritoneum and intraabdominal lymph nodes. He was initially taking WHO category I antituberculous drugs, but was not responding in spite of 5 months of chemotherapy. Culture of the pleural biopsy specimen grew Mycobacterium tuberculosis which was resistant to isoniazid and rifampicin. He was put on therapy for multidrug resistant tuberculosis,following 24 months of chemotherapyhe had an uneventful recovery.

Efficacy of fasting and calorie restriction (FCR) on mood and depression among ageing men

OBJECTIVE

An intervention study on the FCR (Fasting and Calorie Restriction) dietary regime was carried out to determine its efficacy in improving mood states and depression status among ageing men.

SUBJECTS

A total of 32 healthy males (Mean±SD), aged 59.7±6.3 years, with a BMI of 26.7±2.2 kg/m2 were recruited to the study.

METHOD

Participants were randomized to either the FCR group (and were instructed to follow a calorie restricted dietary regime with intermittent fasting) or to the control group (in which individuals were asked to maintain their current lifestyle), for a 3 month period. Mood was assessed using the Profile of Mood States and depression was assessed using Beck Depression Inventory-II and Geriatric Depression Scale-15 at baseline, week 6 and week 12 of the intervention.

RESULTS

A total of 31 subjects completed the study (n=16, FCR and n=15, control). Significant decreases in tension, anger, confusion and total mood disturbance and improvements in vigor were observed in participants in the FCR group compared to the control group (p<0.05). No significant changes in mean depression scores were observed. Weight, BMI and percent body fat were reduced by 3.8%, 3.7% and 5.7% respectively in the FCR group.

CONCLUSIONS

Our findings show that a FCR dietary regime is effective in improving mood states and nutritional status among ageing men.

Leucocytosis in a case of Lung Cancer: Infection or Paraneoplastic Syndrome? - Dilemma in Diagnosis and Treatment

A 65 year old male smoker was diagnosed with squamous cell carcinoma of upper lobe of the right lung complicated with Horner's syndrome and gradually increasing leucocytosis. Alhough the inflammatory biomarker level in serum was low, there was no definite way to determine the cause of the leucocytosis (whether infection or hematologic paraneoplastic syndrome). After empirical antibiotic therapy, his fever subsided but the leucocytosis persisted. It was difficult for us to take a decision regarding the priority of the treatment of infection or the lung cancer. Only after the first cycle chemotherapy, did the leucocytosis rapidly drop down. Normal serum procalcitonin level and quick response to chemotherapy indicated that leucocytosis was a manifestation of paraneoplastic syndrome. Treating the underlying cancer is the first step.

An Unusual Presentation of Adult Onset Still's Disease

Adult onset still's disease usually presents with high grade intermittent fever, polyarthritis, salmon pink evanescent rash and hepatosplenomegaly. Pulmonary involvement in the form of pneumonitis, as a presenting feature is very rare. We report a case of a young lady who presented with fever, cough and respiratory distress. Chest X-ray revealed patchy infiltration in left upper lung zone. She was subsequently diagnosed as Adult onset Still's disease. There was no improvement in clinical condition despite five days of antibiotics. On trans-bronchial lung biopsy (TBLB) proved she had interstitial pneumonitis and responded dramatically to steroid treatment.

Structural and optical properties of glancing angle deposited TiO2 nanowires array

TiO2 nanowires (NWs) have been synthesized by glancing angle deposition technique using e-beam evaporator. The average length 490 nm and diameter 80 nm of NWs were examined by field emission-scanning electron microscopy. Transmission electron microscopy emphasized that the NWs were widely dispersed at the top. X-ray diffraction has been carried out on the TiO2 thin film (TF) and NW array. A small blue shift of 0.03 eV was observed in Photoluminescence (PL) main band emission for TiO2 NW as compared to TiO2 TF. The high temperature annealing at 980 degrees C partially removed the oxygen vacancy from the sample, which was investigated by PL and optical absorption measurements.

HISTOLOGY OF ESOPHAGUS OF BLACK BENGAL GOAT

Detail histological features of esophagus of 12 Black Bengal goats were studied in the Department of Anatomy and Histology, BAU, Mymensingh-2202, Bangladesh during the period from July to December 2003. All specimens were collected from adult Black Bengal goats (over 6 months of age) irrespective of age and sex. The esophagus of Black Bengal goat was sampled at six areas- cranial cervical, middle cervical, caudal cervical, at the level of thoracic inlet, at the middle mediastinum and at the level of cardia. The histological layers of esophagus were-tunica mucosa (lamina epithelia, lamina propria and lamina muscularis mucosa), tunica submucosa, tunica muscularis and tunica scrosa/adventitia.

Skeletal muscle damage and impaired regeneration due to LPL-mediated lipotoxicity

According to the concept of lipotoxicity, ectopic accumulation of lipids in non-adipose tissue induces pathological changes. The most prominent effects are seen in fatty liver disease, lipid cardiomyopathy, non-insulin-dependent diabetes mellitus, insulin resistance and skeletal muscle myopathy. We used the MCK(m)-hLPL mouse distinguished by skeletal and cardiac muscle-specific human lipoprotein lipase (hLPL) overexpression to investigate effects of lipid overload in skeletal muscle. We were intrigued to find that ectopic lipid accumulation induced proteasomal activity, apoptosis and skeletal muscle damage. In line with these findings we observed reduced Musculus gastrocnemius and Musculus quadriceps mass in transgenic animals, accompanied by severely impaired physical endurance. We suggest that muscle loss was aggravated by impaired muscle regeneration as evidenced by reduced cross-sectional area of regenerating myofibers after cardiotoxin-induced injury in MCK(m)-hLPL mice. Similarly, an almost complete loss of myogenic potential was observed in C2C12 murine myoblasts upon overexpression of LPL. Our findings directly link lipid overload to muscle damage, impaired regeneration and loss of performance. These findings support the concept of lipotoxicity and are a further step to explain pathological effects seen in muscle of obese patients, patients with the metabolic syndrome and patients with cancer-associated cachexia.

Ultrashort highly localized wavepackets

The recently introduced concept of radially non-oscillating, temporally stable ultrashort-pulsed Bessel-like beams we referred to as needle beams is generalized to a particular class of highly localized wavepackets (HLWs). Spatio-temporally quasi-nondiffracting pulses propagating along extended zones are shaped from Ti:sapphire oscillator radiation with a spatial light modulator and characterized with spatially resolved second order autocorrelation. Few-cycle wavepackets tailored to resemble circular disks, rings and bars of light represent the closest approximation of linear-optical light bullets known so far. By combining multiple HLWs, complex pulsed nondiffracting patterns are obtained.

Translocator protein (TSPO) in breast cancer

Several molecular and cellular markers are currently used as prognostic indicators for diagnosis and therapeutic intervention of breast cancer. Although some of these markers have helped clinicians provide an earlier diagnosis (or prognosis), they have failed to provide adequate information about the mechanisms responsible for different stages of tumor malignancy so that more effective anticancer therapies can be developed. Recently translocator protein (TSPO), formerly known as the peripheral benzodiazepine receptor (PBR), has received attention as a potential target for anticancer drug development. It is a well-conserved protein, located at outer-inner mitochondrial membrane contact sites, and is expressed in almost all tissues, although the level of expression varies. TSPO is closely associated with the 32 kDa voltage-dependent anion channel (VDAC) and the 30 kDa adenine nucleotide translocase (ANT), considered to form the core of a mitochondria multiprotein complex [named the mitochondrial permeability transition pore (MPTP)] and plays a role in apoptotic cell death. As the major role of TSPO is steroid biosynthesis, TSPO expression is particularly high in organs involved in steroidogenesis such as the adrenals, testes, ovaries, placenta, prostate, colon, kidney, and cardiovascular system. It is well known that TSPO is over-expressed in highly aggressive tumors, especially those of the breast, and that expression correlates with advancing stages of this malignancy. TSPO expression, nuclear localization, and TSPO-mediated cholesterol transport into the nucleus are involved in breast cancer cell proliferation and aggressive phenotype expression. Hence, it can be used as a biomarker in the stage-dependent diagnosis of this cancer. In addition, cell proliferation, invasion and migration appears to be decreased when treated with high doses of TSPO ligand PK-11195, a compound that may represent a therapeutic agent for the control of breast cancer progression. Control of breast cancer development by consumption of dietary soy protein has been linked to down-regulation of the expression of TSPO-mediated angiogenic signaling molecules. This chapter provides insight into the potential of TSPO as a rational target for the development of novel therapeutics for breast cancer.

Studies on the identification and control of pathogen Saprolegnia in selected Indian major carp fingerlings at mid hill altitude

The Indian major carp cultured in ponds in the North Eastern hilly states of India frequently suffer from fungal disease during winter months resulting in mass mortality. This study examined the pathogenic fungi isolated from farmed raised Indian major carp fingerlings and identified as Saprolegnia. For treatment, the diseased fish were exposed to 4g salt per litre of water for 2 min followed by dip treatment with 5ppm KMnO4 for 10 min, thrice every week for a period of 6 weeks. The treatment resulted in recovery from the disease after 6 weeks from the beginning of treatment. Soon after recovery, the pond management practices such as removal of pond bottom soil, application of lime and replenishment with freshwater were followed in the infected ponds. Our study concluded that rapid decrease in pond water temperature from 22 to 8 degrees C that remains low for months together coupled with increased water pH (9) and decreas dissolved oxygen (4ppm) causes saprolegniasis to the fingerlings of Indian major carps.

Tuberculosis of the thyroid gland

We are reporting a case of thyroid gland tuberculosis presenting as a painless hard nodular swelling of the thyroid with concomitant pulmonarytuberculosis in a 53-year-old adult diabetic male. Fine needle aspiration cytology showed epitheloid cell granuloma without any acid fast bacillus. He made an uneventful recovery with anti tuberculous drugs. Though rare, tuberculosis should be considered as a differential diagnosis of nodular or diffuse enlargement of thyroid gland.

Pyoderma Gangrenosum and High Titer Serum Aanti-CCP2 Antibodies

Pyoderma gangrenosum is an uncommon ulcerative cutaneous neutrophilic dermatosis. In about 50 percent of cases, it is associated with systemic diseases like inflammatory bowel disease, rheumatoid arthritis, systemic lupus erythromatosus, hematological diseases and various malignancies. There is no specific laboratory finding or histological features pathognomonic of pyoderma gangrenosum and it is often a diagnosis of exclusion. Here, we report an elderly female without history of any systemic disorders, presenting to us with extensive, bilaterally symmetrical, deep leg ulcers along with multiple superficial ulcers involving the right groin which was diagnosed as pyoderma gangrenosum. The only positive rheumatologic marker was serum anti-cyclic cittrulinated peptide2 antibody, which was found to be strongly positive. Dramatic response to systemic corticosteroid followed by successful split skin grafting was observed in our patient. Keywords: Anti cyclic cittrulinated peptide2, pyoderma gangrenosum, symmetric leg ulcer.

The battery delivered a discharge capacity of 305 mAh g(-1) in the first cycle and 273 mAh g(-1) after 20 cycles, with very stable electrochemical behaviour.

Relationship of severity of depression, anxiety and stress with severity of fibromyalgia

OBJECTIVES

Negative affects like depression, anxiety and stress are frequently observed in patients with fibromyalgia (FMS). Understanding the association between FMS and negative affects is likely to help in deciding the choice of treatment. The aim of this study was to determine the correlation between the severity of FMS with the severity of depression, anxiety and stress.

METHODS

Sixty patients with fibromyalgia and 60 healthy controls were included in the study. Fibromyalgia Impact Questionnaire Revised (FIQR), and Depression, Anxiety and Stress Scale (DASS21) were administered to both the groups. The mean age of study population was 40.4±9.9 and 36±8.7 for FMS and control groups respectively. Most of the patients were females (93.3%).

RESULTS

In subjects without FMS, depression was seen in 5% and was significantly associated with all three components of FIQR (p<0.01), namely pain, symptoms and functional impairment. However, patients with FMS suffered more from all three components assessed in FIQR than those without FMS. In patients with FMS the severity of depression, anxiety and stress were found significantly associated with the severity of all three components of FIQR, namely pain, function and symptoms (p<0.01).

CONCLUSIONS

Results suggest that FMS is associated with depression, anxiety and stress and in FMS magnitude of negative affects is significantly correlated with FIQR. However, depression alone in absence of FMS can also give rise to all three components of FIQR.

Is aorto-arteritis a manifestation of primary antiphospholipid antibody syndrome?

A 23 year old female presented with dyspnea on exertion and absent pulses in the left upper limb. She had prior history of two first trimester abortions and pre-eclampsia with premature delivery. A Doppler examination had revealed left subclavian and axillary artery thrombosis for which she had been given warfarin six months previously. She was admitted and investigated. Patient had low positive aCL IgG antibody, positive antibeta2gp1 antibody, negative lupus anticoagulant and negative ANA. Patient had cardiomegaly and her echocardiography showed severe aortic regurgitation, moderate mitral regurgitation and moderate pulmonary artery hypertension with poor ejection fraction with normal aortic root. A diagnosis of primary antiphospholipid antibody syndrome with valvular involvement with dilated cardiomyopathy was entertained. A CT angiogram of the aorta revealed narrowing and irregularity of the aorta and its multiple branches suggestive of type III Takayasu's arteritis. Temporal relationship suggests development of aorto-arteritis secondary to APS but simultaneous presence of both these disorders in this patient cannot be ruled out.

Psychometric properties of Bengali version of QOLIE-10 in epileptic patients

Assessment of Quality of Life in Epilepsy has currently been emphasized to provide comprehensive care to patients.

Milwaukee shoulder syndrome

Milwaukee shoulder syndrome or rapid destructive arthritis of the shoulder; is a particular form of arthritis which affects mainly elderly patients, predominantly women, with limited pain and sometimes neuropathic joints, rotator cuff tear, joint instability, mildly inflammatory or noninflammatory, blood-stained effusion, calcium apatite crystals, and marked joint and bone destruction. This is very uncommon condition and very sparsely reported and so far, there is no case report from India, hence, we report a case of Milwaukee shoulder syndrome from India.

Comparison of haematological parameters in patients with non-alcoholic fatty liver disease and alcoholic liver disease

INTRODUCTION

Readily available laboratory tests are extremely useful in achieving a better understanding of diseases, and thereby, allow thoughtful management decisions to be made. The examination of peripheral blood smears usually provides excellent clues to the cause of the disease. The main objective of this study was to compare the haematological parameters of patients with non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD), and assess whether these tests have any discriminant value between the two conditions.

METHODS

The haematological parameters were investigated in 105 NAFLD patients, 40 ALD patients, 32 alcoholics and 77 normal participants.

RESULTS

The haemoglobin, red blood cell, haematocrit, lymphocyte count and platelet count were significantly reduced, while the mean corpuscular volume, mean corpuscular haemoglobin and prothrombin time expressed as an international normalised ratio (PT/INR) were significantly elevated in ALD patients compared to the other groups. The platelet count was significantly reduced, while the PT/INR and erythrocyte sedimentation rate (ESR) were significantly elevated in alcoholics compared to normal participants. ESR was also significantly elevated in ALD patients compared to normal participants and NAFLD patients. Compared to the control group, the NAFLD patients have significantly higher haematocrit and significantly lower platelet count.

CONCLUSION

Chronic alcoholism is associated with inflammation and haematotoxic effects, while NAFLD has limited effect on haematological parameters.

POEMS Syndrome

A 49 years old male patient admitted with 2 years history of lower extremity symmetrical sensorimotor polyneuropathy, sclerodermic skin change, erectile dysfunction, hepatosplenomegaly and monoclonal gammopathy. The clinical evaluation met the criteria for the diagnosis of (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, skin changes) POEMS syndrome. The patient was treated with corticosteroid and melphelan and responded well. We present a case different from the other cases with severe unusual burning sensation all over the body, which was his sole complaint and with this complaint he visited lot of doctors including psychiatrist.
