Abstract
The present investigation was conducted to assess the nutritional diverseness and identify novel genetic resources to be utilized in chickpea breeding for macro and micro nutrients. The plants were grown in randomized block design. Nutritional and phytochemical properties of nine chickpea genotypes were estimated. The EST sequences from NCBI database were downloaded in FASTA format, clustered into contigs using CAP3, mined for novel SSRs using TROLL analysis and primer pairs were designed using Primer 3 software. Jaccard's similarity coefficients were used to compare the nutritional and molecular indexes followed by dendrograms construction employing UPGMA approach. The genotypes PUSA-1103, K-850, PUSA-1108, PUSA-1053 and the EST-SSR markers including the 5 newly designed namely ICCeM0012, ICCeM0049, ICCeM0067, ICCeM0070, ICCeM0078, SVP55, SVP95, SVP96, SVP146, and SVP217 were found as potential donor/marker resources for the macro-micro nutrients. The genotypes differed (p < 0.05) for nutritional properties. Amongst newly designed primers, 6 were found polymorphic with median PIC (0.46). The alleles per primer ranged 1 to 8. Cluster analysis based on nutritional and molecular diversities partially matched to each other in principle. The identified novel genetic resources may be used to widen the germplasm base, prepare maintainable catalogue and identify systematic blueprints for future chickpea breeding strategies targeting macro-micro nutrients.

Abstract
A woman with autoimmune hemolytic anemia (AIHA) presented in the emergency department with life-threatening anemia (hemoglobin 3 g/dL). Exaggeration of preexisting chronic anemia to severe anemia after a recent red blood cell (RBC) transfusion led to suspicion of delayed hemolytic transfusion reaction. Given the urgency for transfusion along with a stronger suspicion for coexistence of an alloantibody, the dilution method proposed by Lawrence Petz and George Garratty was used to find an RBC unit for transfusion. An alloantibody with Fyb specificity was identified, which was masked by the coexistent autoantibody. This method is based on the assumption that the titers of an alloantibody are higher than that of autoantibody. Diluting the autoantibody would reveal the alloantibody and, for this purpose, a serial doubling dilution of serum is performed. This method has an important limitation of missing any alloantibodies with titers less than that of the autoantibody. In spite of this, this method may be of use at a resource-poor setting, where trained personnel and other reagents intended for advanced immunohematology methods are unavailable.

Abstract
Guava (Psidium guajava L.) is one of the most important tropical fruits belonging to
the genus Psidium and the Myrtaceae family and claim to have phenolic compounds
that have been reported to possess strong antioxidant activity. This study was aimed to
evaluate the bioactive constituents in guava cultivars at different ripening stages by
HPLC. The five guava cultivars were selected at different ripening stages and the
bioactive components were analysed by high-pressure liquid chromatography. The
quantification of bioactive compounds revealed that the highest amount of bioactive
compounds was found in cultivar Safeda at the unripe stage, while a minimum amount
was found in ripe Apple Colour guava cultivar. The six bioactive compounds were
quantified in the range of gallic acid (9.46-63.08 mg/100 g), quercetin (0.11-2.51
mg/100 g), myrcetin (0.09-0.034 mg/100 g), ascorbic acid (7.45-75.07 mg/100 g),
apegenin (0.01-0.032 mg/100 g) and lycopene (0.34-0.92 mg/100 g). The exploratory
evaluation of guava samples was performed through Principal Component Analysis
(PCA), the bioactive compounds, lycopene, myricetin, and quercetin are dominant
variables on this PC1 (61.52%) (Scores better than 0.7), thereby causing greater
variability among these samples. The second principal component (PC2) represents
16.54% of the total variance and the ascorbic acid, gallic acid and apeginin (score
better than 0.7), are the dominant variables on this PC.

Abstract
Background Rifampicin resistant tuberculosis (RR-TB) was frequently detected in Suriname after the introduction of Xpert MTB/RIF in 2012. Subsequent phenotypic drug-susceptibility testing (DST) was not conclusive at that moment, while RR-TB patients treated with first-line tuberculostatics had good treatment outcome. In our study, we analysed this interesting observation. Methods We collected demographic and clinical characteristics and treatment outcome of TB patients from May 2012-December 2018 and performed a univariate and multivariate analysis to assess possible associations with resistance to rifampicin. Secondly, we conducted whole genome sequencing on all available Mycobacterium tuberculosis isolates that had a rifampicin resistance in the Xpert MTB/RIF test and performed phenotypic DST on selected isolates. Findings RR-TB was detected in 59 (9.6%) patients confirmed by Xpert. These patients were treated with rifampicin-containing regimens in most (88%) of the cases. In all 32 samples examined, a D435Y mutation in the rpoB gene was identified; only one isolate revealed an additional isoniazid mutation. Phenotypic DST indicated low-level rifampicin resistance. In multivariate analysis, the Creole ethnicity was a factor associated with rifampicin resistance (aOR 3.5; 95%CI 1.9–6.4). The treatment success rate for patients with RR-TB (78.0%) was comparable to the treatment outcome in non-RR-TB patients 77.8%. Interpretation This study confirms a low-level rifampicin mono-resistance in TB patients of Suriname. These patients could benefit from a first-line regimen with high dose rifampicin (or rifabutin), rather than from the lengthy treatment regimens for rifampicin-resistant and multi-drug resistant TB, a concept of stratified medicine also advocated for the treatment of TB. Funding None.

Abstract
Abstract
A multilaboratory collaborative study was conducted to compare the detection of Salmonella by the Assurance GDS® for Salmonella method and the Reference culture methods. Six foods, representing a variety of low microbial and high microbial load foods were analyzed. Seventeen laboratories in the United States and Canada participated in this study. No statistical differences (P < 0.05) were observed between the Assurance GDS for Salmonella and the Reference culture methods for any inoculation level of any food type or naturally contaminated food, except for pasta, for which the Assurance GDS method had a higher number of confirmed test portions for Salmonella compared to the Reference method.

Abstract
The 3M™ Petrifilm™ Staph Express Count plate method was compared with AOAC Official Method 975.55 for the enumeration of Staphylococcus aureus in selected foods. Four foods—cooked, diced chicken; cured ham; smoked salmon; and pepperoni—were analyzed for S. aureus by 12 collaborating laboratories. For each food tested, the collaborators received 8 blind test samples consisting of a control sample, a low inoculation level, a medium inoculation level, and a medium inoculation level with background flora, each in duplicate. The mean log10 counts for the methods were comparable for all 4 foods. The repeatability and reproducibility variances of the 24 h Petrifilm Staph Express Count plate method were similar to those of the 72 h standard method.

Abstract
BACKGROUND Meiotic abnormalities lead to morphological and genetic variations which caused not only to evolution but also intraspecific reproductive barriers. During present study of detailed meiotic course in dicotyledonous plants sampled from Indian cold deserts, various meiotic abnormalities have been detected. For this, the plant materials fixed in Carnoy's fixative and studied detailed meiotic course by standard squash method in 1% acetocarmine. RESULTS Meiotic abnormalities have been presently detected in 71 species which include multiple associations in diploids (Achillea millefolium L.), multivalents and univalents in polyploids (4 species), cytomixis (40 species), chromosome stickiness (20 species), nonsynchronous disjunction of bivalents (32 species), interbivalent connections (15 species), synaptic mutants (2 species), syncyte meiocytes (2 species), abnormal spindles (7 species), and fusion of pollen grains (1 species), laggards and chromatin bridges, hypo-, hyperploid PMCs, monads, dyads, triads, tetrads with micronuclei and polyads. CONCLUSIONS Consequently, variable sized apparently fertile pollen grains and considerable amount of sterile pollen grains are resulted as end products which lead to different genetic constitution (aneuploids and polyploids) and curtailed sexual reproductive success in these species.

Abstract
Caesarean scar pregnancy is one of the rarest forms of ectopic pregnancy. Transvaginal ultrasound and color flow Doppler provides a high diagnostic accuracy. A delay in diagnosis and treatment can lead to uterine rupture, major hemorrhage, hysterectomy and serious maternal morbidity and mortality. Early diagnosis can offer treatment options of avoiding uterine rupture and hemorrhage, thus preserving the uterus and future fertility. Primary health care provider should know about this rare entity, because if diagnosed timely, and referral to specialized centre is done without delay will definitely save maternal morbidity and mortality. Management plan should be individualized. Termination of pregnancy is the treatment of choice in the first trimester. Expectant treatment has a poor prognosis because of risk of rupture. In this case report we aim to discuss the associated diagnostic dilemma, most appropriate methods of diagnosis and management, with their implications in clinical practice.

Abstract
Incidence of Buxtonella sulcata was recorded as 20.9 % in bovines (n = 374) of R.S. Pura, Jammu with cattle showing higher infection rate (23.6 %) than the buffaloes (18.5 %). The infection was significantly (p < 0.0001) higher in young animals (33.1 %) than the adults (13.9 %). Animals with diarrhoeic faeces had a significantly higher (p < 0.0001) infection rate (38.5 %) than the animals with normal faeces (9.9 %), suggesting the influence of protozoan on the incidence of diarrhoeal symptoms in bovines.

Abstract
Background Mast cell localization within the airway smooth muscle (ASM)-bundle plays an important role in the development of airway hyper-responsiveness (AHR). Genomewide association studies implicate the ‘alarmin’ IL-33 in asthma, but its role in mast cell–ASM interactions is unknown. Objectives We examined the expression and functional role of IL-33 in bronchial biopsies of patients with and without asthma, ex vivo ASM, mast cells, cocultured cells and in a mouse model system. Methods IL-33 protein expression was assessed in human bronchial tissue from 9 healthy controls, and 18 mild-to-moderate and 12 severe asthmatic patients by immunohistochemistry. IL-33 and ST2 mRNA and protein expression in human-derived ASM, epithelial and mast cells were assessed by qPCR, immunofluorescence and/or flow cytometry and ELISA. Functional assays were used to assess calcium signalling, wound repair, proliferation, apoptosis and contraction. AHR and inflammation were assessed in a mouse model. Results Bronchial epithelium and ASM expressed IL-33 with the latter in asthma correlating with AHR. ASM and mast cells expressed intracellular IL-33 and ST2. IL-33 stimulated mast cell IL-13 and histamine secretion independent of FcεR1 cross-linking and directly promoted ASM wound repair. Coculture of mast cells with ASM activated by IL-33 increased agonist-induced ASM contraction, and in vivo IL-33 induced AHR in a mouse cytokine installation model; both effects were IL-13 dependent. Conclusion IL-33 directly promotes mast cell activation and ASM wound repair but indirectly promotes ASM contraction via upregulation of mast cell-derived IL-13. This suggests that IL-33 may present an important target to modulate mast cell–ASM crosstalk in asthma.

Abstract
The aim of the study was to evaluate the in vitro efficacy of different concentrations of ethanolic extract obtained from the aerial parts of Artemisia absinthium in comparison to amitraz on adults, eggs and larvae of Hyalomma anatolicum using the adult immersion test (AIT), egg hatchability test and larval packet test (LPT), respectively. Four concentrations of the extract (2.5, 5, 10 and 20%) with three replications for each concentration were used in all the bioassays. In AIT, the mortality rates at 2.5, 5 and 10% were significantly different (p < 0.05) in comparison to the control group; however, at 20%, it was similar to the positive control group. Maximum mortality of 86.7% was recorded at 20%. The LC50 and LC95 values were calculated as 6.51 and 55.43%, respectively. The oviposition was reduced significantly by 36.8 and 59.1% at concentrations of 10 and 20%, respectively. Egg hatchability was reduced significantly at all concentrations (2.5-20%) in comparison to the control. In LPT, the extract caused 100% mortality of larvae at all the concentrations after 24 h. The results show that ethanolic extract obtained from the aerial parts of A. absinthium has acaricidal properties and could be useful in controlling H. anatolicum.

Abstract
BACKGROUND Asthma is characterized by variable airflow obstruction, airway inflammation, airway hyper-responsiveness and airway remodelling. Airway smooth muscle (ASM) hyperplasia is a feature of airway remodelling and contributes to bronchial wall thickening. We sought to investigate the expression levels of chemokines in primary cultures of ASM cells from asthmatics vs healthy controls and to assess whether differentially expressed chemokines (i) promote fibrocyte (FC) migration towards ASM and (ii) are increased in blood from subjects with asthma and in sputum samples from those asthmatics with bronchial wall thickening. METHODS Chemokine concentrations released by primary ASM were measured by MesoScale Discovery platform. The chemokine most highly expressed by ASM from asthmatics compared with healthy controls was confirmed by ELISA, and expression of its cognate chemokine receptor by FCs was examined by immunofluorescence and flow cytometry. The role of this chemokine in FC migration towards ASM was investigated by chemotaxis assays. RESULTS Chemokine (C-C motif) ligand 2 (CCL2) levels were increased in primary ASM supernatants from asthmatics compared with healthy controls. CCR2 was expressed on FCs. Fibrocytes migrated towards recombinant CCL2 and ASM supernatants. These effects were inhibited by CCL2 neutralization. CCL2 levels were increased in blood from asthmatics compared with healthy controls, and sputum CCL2 was increased in asthmatics with bronchial wall thickening. CONCLUSIONS Airway smooth muscle-derived CCL2 mediates FC migration and potentially contributes to the development of ASM hyperplasia in asthma.

Abstract
The objective of the study was to evaluate the in vitro efficacy of different concentrations of chloroform extract obtained from the aerial parts of Artemisia absinthium in comparison to amitraz on adults, eggs and larvae of the dog tick Rhipicephalus sanguineus using the adult immersion test (AIT), egg hatchability test (EHT) and larval packet test (LPT), respectively. Five concentrations of the extract (1.25, 2.5, 5, 10 and 20 %) with three replications for each concentration were used in all the bioassays. A control group was established (water + dimethylsulphoxide) together with a positive control group (amitraz), with three repetitions each. In AIT, the mortality rates were 0.0, 13.3, 16.7, 33.3 and 93.3 % in concentrations of 1.25, 2.5, 5, 10 and 20 %, respectively, and the variation was significant (p=0.0151). The LC50 (CI) and LC95 (CI) values were calculated as 8.793 % (8.217-9.408) and 34.59 % (29.71-40.26), respectively. The egg production was reduced by 6.6, 6.6, 18.3, 42.5 and 85.1 % in the concentrations of 1.25, 2.5, 5, 10 and 20 %, respectively, and it was statistically significant (p=0.0274). In EHT, hatching was completely inhibited at 5, 10 and 20 % displaying 100 % ovicidal action while at the concentrations of 1.25 and 2.5 %, the inhibition rates were 20 and 60 %, respectively. In LPT, the extract caused 100 % mortality of larvae in the concentrations of 5, 10 and 20 % after 24 h while at the concentrations of 1.25 and 2.5 %, the mortality rates were 54.3 and 96.7 %, respectively. The LC50 (CI) and LC95 (CI) values were determined to be 1.11 % (1.099-1.121) and 2.37 % (2.328-2.423), respectively. The results show that the extract of A. absinthium has acaricidal properties and could be useful in controlling R. sanguineus which is an efficient vector of pathogens both in dogs and humans.

Abstract
The present investigation reports the occurrence of filarial worm, Setaria digitata, recovered during the surgery of a cow suffering from intussusception. The worms were thread like, milky white, long with tapering ends especially towards the hind end with an average size of 62.8 ± 9.89 mm in length. On examination of anterior end, the cuticular rings surrounding the mouth region with dorsal, ventral and lateral prominences were observed. The posterior end had few spines along with a pair of appendages near the tip of the tail. On the basis of morphological characteristics the worms were identified as female S. digitata.

Abstract
BACKGROUND Heat shock proteins (Hsps) are evolutionary ancient and highly conserved molecular chaperons found in prokaryotes as well as eukaryotes. Hsp70 is a predominant member of Hsp family. Microbial Hsp70s (mHsp70s) have acquired special significance in immunity since they have been shown to be potent activators of the innate immune system and generate specific immune responses against tumours and infectious agents. OBJECTIVES The present study was aimed to clone express and purify recombinant Hsp70 from the Mycobacterium tuberculosis and characterise it immunologically. The study also aimed at determining the potential of recombinant M. tuberculosis heat shock protein (rMTB-Hsp70) as adjuvant or antigen carrier. MATERIALS AND METHODS Cloning of M. tuberculosis heat shock protein (MTB-Hsp70) amplicon was carried out using the pGEMT-Easy vector although for expression, pProExHTb prokaryotic expression vector was used. Purification of recombinant Hsp70 was carried out by nickel-nitrilotriacetic acid (Ni-NTA) affinity chromatography. For immunological characterization and determining the adjuvant effect of MTB-Hsp70, BALB/c mice were used. The data obtained was statistically analysed. RESULTS Hsp70 gene was cloned, sequenced and the sequence data were submitted to National Center for Biotechnology Information (NCBI). Recombinant MTB-Hsp70 was successfully over-expressed using the prokaryotic expression system and purified to homogeneity. The protein was found to be immunodominant. Significant adjuvant effect was produced by the rMTB-Hsp70 when inoculated with recombinant outer membrane protein 31; however, effect was less than the conventionally used the Freund's adjuvant. CONCLUSION Protocol standardised can be followed for bulk production of rHsp70 in a cost-effective manner. Significant adjuvant effect was produced by rMTB-Hsp70; however, the effect was than Freund's adjuvant. Further, studies need to be carried out to explore its applicability as carrier of antigen.

Abstract
A variation in the course of the thoracic duct was found in the cervical portion of a male cadaver during routine dissection of the head and neck region for undergraduate students. The thoracic duct, while arching laterally above the clavicle, was coursing posterior to the vertebral vein but anterior to the vertebral artery; it normally passes anterior to both the vertebral vein and artery. To the best of our knowledge, this variation in relation to the vertebral vein has not yet been reported. In addition, after coursing posterior to the vertebral vein, the thoracic duct divided into two branches that drained separately, one at the angle between the internal jugular vein and subclavian vein, and the other into the subclavian vein. Knowledge of these variations is essential in order to prevent injury to the thoracic duct while performing surgeries at the root of the neck.

Abstract
Background Airway smooth muscle (ASM) hyperplasia and mast cell localization within the ASM bundle are important features of asthma. The cause of this increased ASM mass is uncertain and whether it is a consequence of ASM–mast cell interactions is unknown. Objective We sought to investigate ASM proliferation and survival in asthma and the effects of co-culture with mast cells. Methods Primary ASM cultures were derived from 11 subjects with asthma and 12 non-asthmatic controls. ASM cells were cultured for up to 10 days in the presence or absence of serum either alone or in co-culture with the human mast cell line-1, unstimulated human lung mast cells (HLMC) or IgE/anti-IgE-activated HLMC. Proliferation was assessed by cell counts, CFSE assay and thymidine incorporation. Apoptosis and necrosis were analysed by Annexin V/propidium iodide staining using flow cytometry and by assessment of nuclear morphology using immunofluorescence. Mast cell activation was confirmed by the measurement of histamine release. Results Using a number of techniques, we found that ASM proliferation and survival was not significantly different between cells derived from subjects with or without asthma. Co-culture with mast cells did not affect the rate of proliferation or survival of ASM cells. Conclusion Our findings do not support a role for increased airway smooth proliferation and survival as the major mechanism driving ASM hyperplasia in asthma. Cite this as: D. Kaur, F. Hollins, R.

Abstract
BACKGROUND Chemokine receptors play an important role in cell migration and wound repair. In asthma, CCR3 and 7 are expressed by airway smooth muscle (ASM) and CCR7 has been implicated in the development of ASM hyperplasia. The expression profile of other chemokine receptors by ASM and their function needs to be further explored. OBJECTIVE We sought to investigate ASM chemokine receptor expression and function in asthma. METHODS ASM cells were derived from 17 subjects with asthma and 36 non-asthmatic controls. ASM chemokine receptor expression was assessed by flow cytometry and immunofluorescence. The function of chemokine receptors expressed by more than 10% of ASM cells was investigated by intracellular calcium measurements, chemotaxis, wound healing, proliferation and survival assays. RESULTS In addition to CCR3 and 7, CXCR1, 3 and 4 were highly expressed by ASM. These CXC chemokine receptors were functional with an increase in intracellular calcium following ligand activation and promotion of wound healing [CXCL10 (100 ng/mL) 34 +/- 2 cells/high-powered field (hpf) vs. control 29 +/- 1; P=0.03; n=8]. Spontaneous wound healing was inhibited by CXCR3 neutralizing antibody (mean difference 7 +/- 3 cells/hpf; P=0.03; n=3). CXC chemokine receptor activation did not modulate ASM chemotaxis, proliferation or survival. No differences in chemokine receptor expression or function were observed between ASM cells derived from asthmatic or non-asthmatic donors. CONCLUSIONS Our findings suggest that the chemokine receptors CXCR1, 3 and 4 modulate some aspects of ASM function but their importance in asthma is uncertain.

Abstract
OBJECTIVE To study the feasibility and acceptability of Kangaroo mother care (KMC) on the low birth weight infants (LBWI) in the neonatal intensive care unit (NICU) by the mothers, family members and health care workers (HCW) and to observe its effect on the vital parameters of the babies. METHOD A observation in the NICU. RESULTS A total of 135 babies (74 boys and 61 girls) who completed minimum of 4 hrs of KMC/day, were included. The mean birth weight and gestation were 1460 gm and 30 week respectively. 47% babies started KMC within first week of age. Mean duration of KMC was 7 days (3-48) days. The O(2) saturation improved by 2-3%, temperature ( degrees C) rose from 36.75 +/- 0.19 to 37.23 +/- 0.25, respiration stabilized (p<0.05 for all) and heart rate dropped by 3-5 beats. No episodes of hypothermia or apnea were observed during KMC. KMC was accepted by 96 % mothers, 82% fathers and 84% other family members. 94% HCW considered it to be safe and conservative method of care of LBWI. Benefits of KMC on the babies' behavior and on maternal confidence and lactation were reported by 57%, 94% and 80% respectively. A decline in use of heating devices in the NICU was reported by 85% and 79% said it did not increase their work load. CONCLUSION KMC was found to be safe, effective and feasible method of care of LBWI even in the NICU settings. Positive attitudes were observed in mothers, families and HCW.

Abstract
BACKGROUND Airway smooth muscle hyperplasia is a feature of asthma, and increases with disease severity. CCR3-mediated recruitment of airway smooth muscle progenitors towards the airway smooth muscle bundle has been proposed as one possible mechanism involved in airway smooth muscle hyperplasia. Mast cells are microlocalized to the airway smooth muscle bundle and whether mast cells influence CCR3-mediated migration is uncertain. METHODS We examined the expression of CCR3 by primary cultures of airway smooth muscle cells from asthmatics and nonasthmatics. CCR3 function was examined using intracellular calcium measurements, chemotaxis, wound healing, cell proliferation and survival assays. We investigated the recovery and function of both recombinant and airway smooth muscle-derived CCL11 (eotaxin) after co-culture with beta-tryptase and human lung mast cells. RESULTS Airway smooth muscle expressed CCR3. Airway smooth muscle CCR3 activation by CCL11 mediated intracellular calcium elevation, concentration-dependent migration and wound healing, but had no effect on proliferation or survival. Co-culture with beta-tryptase or mast cells degraded recombinant and airway smooth muscle-derived CCL11, and beta-tryptase inhibited CCL11-mediated airway smooth muscle migration. CONCLUSIONS CCL11 mediates airway smooth muscle migration. However co-culture with beta-tryptase or mast cells degraded recombinant and airway smooth muscle-derived CCL11 and inhibited CCL11-mediated airway smooth muscle migration. Therefore these findings cast doubt on the importance of the CCL11/CCR3 axis in the development of airway smooth muscle hyperplasia in asthma.

Abstract
OBJECTIVE To study the variation of the menopause rating scale (MRS) scores with age, working/non-working and educated/uneducated status in a cohort of north-Indian subpopulation and to look for the possible reasons for the incurred variations. MRS is a well-known and validated instrument for assessing the frequency and intensity of menopausal symptoms. METHOD A menopause clinic was organized in collaboration with a primary care centre (under the guidance of a gynecologist). A random sample of 208 women aged 35-65 years participated in the study. The MRS scale, a self-administered standardized questionnaire was applied with additional patient related information (age at menopause, level of education, working/non-working and exercising or not). RESULTS The results were evaluated for psychological (P), somatic (S), and urogenital (U) symptoms. The average age at which menopause set in, in the cohort was found to be 48.7+/-2.3 years (46.4-51 years). Based on the average age at the menopause, the cohort was divided into peri (35-45), menopausal/early menopause (46-51) and the postmenopausal (52-65) groups. A significantly higher % of perimenopausal women (36%) showed a P score of > or =7; while a higher % of postmenopausal showed S score and U score > or =7 (>40%; p< or =0.001). Working women seem to suffer more from psychological symptoms whereas non-working women showed a greater incidence of somatic symptoms. Educated women showed a lower incidence of psychological and somatic symptoms. CONCLUSIONS Present study indicates that age, level of education and working/non-working status (in a group of women with same socio-cultural background) may also contribute to significant variations in menopausal symptoms.

Abstract
BACKGROUND The Th2 cytokine interleukin (IL)-13 is implicated in the development of various allergic diseases including asthma. The IL-13 receptor, IL-13Ralpha1, is expressed on most leukocytes, except T-cells. Evidence to support IL-13Ralpha1 expression on mast cells is limited. METHODS We investigated: (i) IL-13Ralpha1 expression by human lung mast cells (HLMC); (ii) the number of IL-13Ralpha1+ bronchial submucosal mast cells in subjects with asthma and normal controls and (iii) the effect of IL-13 priming on HLMC expression of high-affinity IgE receptor (FcepsilonRI), stem cell factor receptor (CD117), histamine release, proliferation, and survival. RESULTS Human lung mast cell expressed IL-13Ralpha1 mRNA. IL-13Ralpha1 was highly expressed on the surface HLMC (82+/-9%). Bronchial submucosal mast cell IL-13Ralpha1 expression was higher in asthmatics (86+/-2%) than normal controls (78+/-2%; P=0.015). IL-13 priming for 30 min did not increase HLMC histamine release, in the presence or absence of SCF or in response to IgE/anti-IgE activation. IL-13 priming for 5 days upregulated HLMC FcepsilonRI expression (22% increase in fluorescent intensity; P=0.003), increased histamine release following IgE/anti-IgE activation by 56% (P=0.03) and increased proliferation by 50% (P=0.003) without affecting cell survival or CD117 expression. The IL-13 specific neutralizing antibody CAT-354 inhibited all IL-13 mediated effects. CONCLUSION Human lung mast cell express IL-13Ralpha1 and activation by IL-13 for 5 days increased FcepsilonRI expression and proliferation. Histamine release was not affected by short-term priming with IL-13, but was upregulated by priming for 5 days suggesting that this effect was mediated by the increased FcepsilonRI expression. These data support the view that targeting IL-13 may be beneficial in the treatment of asthma.

Abstract
BACKGROUND Mast cell microlocalisation within the airway smooth muscle (ASM) bundle is an important determinant of the asthmatic phenotype. We hypothesised that mast cells migrate towards ASM in response to ASM derived chemokines. METHODS Primary ASM cultures from subjects with and without asthma were stimulated with interleukin (IL)-1beta, IL-4, and IL-13 alone and in combination. Mast cell chemotaxis towards these ASM supernatants was investigated, and the chemotaxins mediating migration by using specific blocking antibodies for stem cell factor (SCF) and the chemokine receptors CCR3, CXCR1, 3 and 4 as well as the Gi inhibitor pertussis toxin and the tyrosine kinase inhibitor genistein were defined. The concentrations of CCL11, CXCL8, CXCL10, TGF-beta, and SCF in the supernatants were measured and the effect of non-asthmatic ASM supernatants on the mast cell chemotactic activity of asthmatic ASM was examined. RESULTS Human lung mast cells and HMC-1 cells migrated towards Th2 stimulated ASM from asthmatics but not non-asthmatics. Mast cell migration was mediated through the combined activation of CCR3 and CXCR1. CCL11 and CXCL8 expression by ASM increased markedly after stimulation, but was similar in those with and without asthma. ASM supernatants from non-asthmatics inhibited mast cell migration towards the asthmatic ASM supernatant. CONCLUSION Th2 stimulated ASM from asthmatics is chemotactic for mast cells. Non-asthmatic ASM releases a mediator or mediators that inhibit mast cell migration towards stimulated asthmatic ASM. Specifically targeting mast cell migration into the ASM bundle may provide a novel treatment for asthma.

Abstract
Three abortigenic Indian isolates of equine herpesvirus-1 (EHV-1) (Tohana, Hisar and Bikaner), along with two exotic abortigenic isolates (AB4 and V592) and another EHV-1 isolate (Jind) obtained from a case of perinatal foal mortality, were studied for variability. For this purpose, PCR and restriction endonuclease (RE) digestion techniques were used simultaneously as a DNA fingerprinting system. Nine different regions of EHV-1 virus were amplified by PCR using primer pairs specific for the regions and the products obtained from these regions were subsequently subjected to various restriction endonucleases to further assess the variability in the number of RE sites as well as in their positions. No difference was observed in all the four abortigenic isolates in terms of the size of different PCR products amplified by all the nine primer pairs, except for primer pairs 'E' and 'C'. PCR products obtained with primer pair E revealed that Tohana and Bikaner isolates were most similar while Hisar isolate was like V592 isolate. However, the PCR product obtained from Jind isolate had a size between the PCR products of Hisar and Tohan/Bikaner isolates. The primer pair 'C' used to amplify the region between 1151 to 3679 in 'Gene 1,2,3' clearly differentiated the EHV-1 isolate obtained from a case of perinatal foal mortality from isolates obtained from abortion cases. This primer pair needs to be exploited more extensively for use as a potential marker for differentiating the EHV-1 isolates, mainly the abortion cases from perinatal foal mortality ones. Restriction endonuclease studies done with PCR product of all the isolates with various primer pairs did not reveal any changes in the position or number of RE sites present in the products amplified, indicating no variation in different RE sites within the amplified PCR products. However, this study clarified that all the Indian isolates belonged to the IP group of EHV-1.
