Genome-wide association study (GWAS) of major QTLs for bunch and oil yield related traits in Elaeis guineensis L

Oil palm (Elaeis guineensis Jacq.) is a long breeding cycle perennial crop with a genome size of 1.8 Gb. This is the first report of GWAS on large number of 310 African germplasm using 400 SSR markers till date. Highly significant correlation was found between leaf area (LA) and rachis length (RL) (0.75) followed by bunch weight (BW) and bunch index (BI) (0.65), whereas negative correlation was observed between bunch number (BN) and average bunch weight (ABW). First two principal component analysis (PCA) together explained maximum amount of variation (84.5 %). The PCA1 revealed that group 2 (Guinea Bissau and Cameroon) and group 4 (Zambia and Cameroon) genotypes are best suitable for BN, BI and BW traits. GWAS of six bunch yield and seven bunch oil yield traits with SSRs resulted in the identification 43 significant quantitative trait loci (QTLs) by mixed linear model (MLM) approach. Seven SSR loci were found to be linked to oil to dry mesocarp (ODM) on chromosomes 1,4,7,10,12 and 15. The SSR locus mEgCIR1753 for ODM was significantly linked at a p of ≤0.05 which explained 34.6 % of phenotypic variance. The important parameters like ODM, OWM and OB were located on 4, 10, 11 and 15 chromosomes. The leaf area and ODM were associated with candidate genes representing of low-temperature-induced 65 kDa proteins. The identified markers can be effectively used for marker assisted selection of high yielding oil palm genotypes.

Phenomics, genomics of oil palm (Elaeis guineensis Jacq.): way forward for making sustainable and high yielding quality oil palm

Oil palm (Elaeis guineensis Jacq.) is a heterogeneous, perennial crop having long breeding cycle with a genome size of 1.8 Gb. The demand for vegetable oil is steadily increasing, and expected that nearly 240-250 million tons of vegetable oil may be required by 2050. Genomics and next generation technologies plays crucial role in achieving the sustainable availability of oil palm with good yield and high quality. A successful breeding programme in oil palm depends on the availability of diverse gene pool, ex-situ conservation and their proper utilization for generating elite planting material. The major breeding methods adopted in oil palm are either modified recurrent selection or the modified reciprocal recurrent selection method. The QTLs of yield and related traits are chiefly located on chromosome 4, 10, 12 and 15 which is discussed in the current review. The probable chromosomal regions influencing the less height increment is observed to be on chromosomes 4, 10, 14 and 15. Advanced genomic approaches together with bioinformatics tools were discussed thoroughly for achieving sustainable oil palm where more efforts are needed. Major emphasis is given on oil palm crop improvement using holistic approaches of various genomic tools. Also a road map given on the milestones in the genomics and way forward for making oil palm to high yielding quality oil palm.

A comparative study to evaluate the effect of honey dressing and silver sulfadiazene dressing on wound healing in burn patients

To compare the effect of honey dressing and silver-sulfadiazene (SSD) dressing on wound healing in burn patients. Patients (n=78) of both sexes, with age group between 10 and 50 years and with first and second degree of burn of less than 50% of TBSA (Total body surface area) were included in the study, over a period of 2 years (2006-08). After stabilization, patients were randomly attributed into two groups: ‘honey group’ and ‘SSD group’. Time elapsed since burn was recorded. After washing with normal saline, undiluted pure honey was applied over the wounds of patients in the honey group (n=37) and SSD cream over the wounds of patients in SSD group (n=41), everyday. Wound was dressed with sterile gauze, cotton pads and bandaged. Status of the wound was assessed every third and seventh day and on the day of completion of study. Patients were followed up every fortnight till epithelialization. The bacteriological examination of the wound was done every seventh day. The mean age for case (honey group) and control (SSD group) was 34.5 years and 28.5 years, respectively. Wound swab culture was positive in 29 out of 36 patients who came within 8 hours of burn and in all patients who came after 24 hours. The average duration of healing in patients treated with honey and SSD dressing at any time of admission was 18.16 and 32.68 days, respectively. Wound of all those patients (100%) who reported within 1 hour became sterile with honey dressing in less than 7 days while none with SSD. All of the wounds became sterile in less than 21 days with honey, while tthis was so in only 36.5% with SSD treated wounds. The honey group included 33 patients reported within 24 hour of injury, and 26 out of them had complete outcome at 2 months of follow-up, while numbers for the SSD group were 32 and 12. Complete outcome for any admission point of time after 2 months was noted in 81% and 37% of patients in the honey group and the SSD group. Honey dressing improves wound healing, makes the wound sterile in lesser time, has a better outcome in terms of prevention of hypertrophic scarring and post-burn contractures, and decreases the need of debridement irrespective of time of admission, when compared to SSD dressing.

Identification of QTLs in oil palm (Elaeis guineensis Jacq.) using SSR markers through association mapping

Oil palm (Elaeis guineensis Jacq.) is a perennial vegetable and a high oil-yielding crop (4-6 t/ha). There is a large scope for increasing the oil yield by selecting elite planting material for breeding programme in germplasm evaluation, characterization and utilization. In the present study, a diverse range of 150 oil palm genotypes were characterized using 12 quantitative variables with 54genomic microsatellite markers. A wide variation was observed in the morphological traits among indigenous populations. Highly significantand positive correlations were observed between vegetative dry matter (VDM) and total dry matter (TDM) (0.862), and height and height increment (0.838). The first two principal component analyses explained 67.7% of total variation among morphological traits. The genotypes IC0610001-59 (Pune-2) and IC0610001-60 (Pune-2) were found highly promising based on less height increment, more TDMwith high yield. For the mapping study, general linear model (GLM) approach, quantitative-trait loci (QTL) for annual height increment, number of bunches, bunch yield and bunch index were linked to simple-sequence repeat (SSR) loci mEgCIR3649 with phenotypic variance of 15.08, 10.43, 11.74, 15.39. TDM and VDM were linked to mEgCIR0192 (27.34 and 24.19%), mEgCIR3684 (16.84 and 18.30%), SPSC00163 (18.8 and 15.39%) and mEgCIR0555 (16.47 and 18.81%), with at a significant threshold (P) level of B0.001 and by mixed linear model (MLM) approach. TDM was linked to mEgCIR0555 with phenotypic variance of 20.72%, bunch yield and bunch index were linked to mEgCIR2813 at phenotypic variance of 17.11% and 12.88%, respectively, at a significant threshold (P) level of B0.01.

Development, identification and validation of CAPS marker for SHELL trait which governs dura, pisifera and tenera fruit forms in oil palm (Elaeis guineensis Jacq.)

The oil palm fruit forms (dura, pisifera and tenera) governed by the shell thickness gene (Sh) plays a major role in identification of fruit type and also influences palm oil yield. Identification of desired fruit type is a major asset to the breeders and oil palm workers for applications in breeding, seed certification and to reduce time, space and money spent on identification of fruit form. In the present study, we developed Sh gene specific primer pairs and bulk segregant analysis was done using 300 genomic and 8 genic SSR markers. We identified one cleaved amplified polymorphic site (CAPS) marker for differentiation of oil palm fruit type which produced two alleles (280 and 250bp) in dura genotypes, three alleles in tenera genotypes (550, 280, and 250bp) and one allele in pisifera genotypes (550bp). The shell allele sequencing results showed that two SNPs were present, of which SNP2 contributed for variation of fruit forms. The nucleotide ‘A’ was present in only dura genotypes, where as ‘T’ was present only in pisifera genotypes, which in turn led to the change of amino acid lysine to aspargine. The identified CAPS marker was validated on 300 dura, 25 pisifera and 80 tenera genotypes, 80 dura/ pisifera cross progenies and 60 lines of tenera/ tenera cross progeny. Association mapping of marker data with phenotypic data of eight oil yield related traits resulted in identification of seven significant QTLs by GLM approach, four by MLM approach at a significant threshold (P) level of 0.001. Significant QTLs were identified for fruit to bunch and oil to bunch traits, which explained R² of 12.9% and 11.5% respectively. The CAPS marker used in the present study facilitate selection and timely distribution of desirable high yielding tenera sprouts to the farmers instead of waiting for 4–5 years. This saves a lot of land, time and money which will be a major breakthrough to the oil palm community.

Epidemiological trends of pediatric trauma: A single-center study of 791 patients

AIM

To assess the various epidemiological parameters that influence the causation of trauma as well as the consequent morbidity and mortality in the pediatric age group.

MATERIALS AND METHODS

A prospective study of 791 patients of less than 12 years age, was carried out over a period of 1 year (August 2009 to July 2010), and pediatric trauma trends, with regards to the following parameters were assessed: Age group, sex, mode of trauma, type of injury, place where the trauma occurred and the overall mortality as well as mortality.

RESULTS

Overall trauma was most common in the school-going age group (6-12 years), with male children outnumbering females in the ratio of 1.9:1. It was observed that orthopedic injuries were the most frequent (37.8%) type of injuries, whereas fall from height (39.4%), road traffic accident (27.8%) and burns (15.2%) were the next most common modes of trauma. Home was found out to be the place where maximum trauma occurred (51.8%). Maximum injuries happened unintentionally (98.4%). Overall mortality was found out to be 6.4% (n = 51).

CONCLUSIONS

By knowing the epidemiology of pediatric trauma, we conclude that majority of pediatric injuries are preventable and pediatric epidemiological trends differ from those in adults. Therefore, preventive strategies should be made in pediatric patients on the basis of these epidemiological trends.

Tube sigmoidostomy: a valuable alternative to sigmoidopexy for sigmoid volvulus

OBJECTIVE

To compare the effectiveness of tube sigmoidostomy and sigmoidopexy as effective treatment options for patients with acute uncomplicated sigmoid volvulus.

METHODS

The records of 72 patients with acute uncomplicated sigmoid volvulus with obstruction who were treated by tube sigmoidostomy (Group I: n=32) and sigmoidopexy (Group II: n=40) were reviewed retrospectively. Follow-up period was 22 months (range: 6-51 months).

RESULTS

Results show significant improvement in postoperative tachycardia, respiratory distress and urine output in Group I patients as compared to those in Group II. Most of the clinical parameters of Group I patients normalized by day 3, while it took up to 7 days in Group II patients. Intraabdominal hypertension caused by persistent colonic dilatation after sigmoidopexy was found to be an important determinant of postoperative morbidity. As compared to tube sigmoidostomy, the sigmoidopexy group had delayed recovery, more chances of abdominal fascial dehiscence, and longer hospital stay, as well as more prolonged abdominal discomfort, constipation, and recurrent volvulus rates during follow-up.

CONCLUSION

Tube sigmoidostomy provides both fixation and decompression of the redundant sigmoid colon in the postoperative period while allowing time to recover from massive dilatation and edema caused by prolonged volvulus. Compared with sigmoidopexy for the treatment of uncomplicated sigmoid volvulus, tube sigmoidostomy leads to lesser rates of morbidity and recurrence. Thus, it can be considered as a definitive alternative treatment option for uncomplicated sigmoid volvulus.

Total urogenital sinus mobilization in common cloaca: experience of 25 cases

OBJECTIVE

Common cloaca is a complex anorectal and genitourinary malformation in which the rectum, vagina and urinary tract are fused to form a single channel. Surgical treatment is complicated especially when the channel is long. Our aim was to emphasize the importance of joint mobilization of the urogenital sinus after separation from the rectum. This maneuver avoids separation of the urinary tract from the genital tract, and reduces operating time by more than 60%. The functional and cosmetic results are also excellent.

PATIENTS AND METHODS

We retrospectively reviewed all consecutive cases of persistent cloaca managed by total urogenital mobilization via a posterior sagittal approach during 2005-2009. There were 25 patients, with a median age of 18 months (10 months-3 years). Two patients with a long common channel required additional maneuvers after mobilization to complete the reconstruction. Each patient had a primary covering colostomy. After distal loop colograms, genitograms, renal ultrasound and genitoscopy, patients were planned for definitive surgery at 1-3 years of age.

CONCLUSION

Total urogenital sinus mobilization in cases of common cloaca represents a surgical advance, and is a promising procedure with reasonably good results for this complex anomaly.

Paediatric pancreatic problems: a five-year experience

BACKGROUND

To analyse a tertiary care experience with various pancreatic problems in the paediatric age group and clarify the frequency of various pancreatic diseases in the same patient population as well as the role of surgical or conservative management in their treatment.

PATIENTS AND METHODS

All patients with clinical suspicion of disease pertaining to the pancreas, substantiated by laboratory investigations or imaging modalities over a period of five years are included in our study.

RESULTS

Of the total 228 patients with various pancreatic problems, who presented to us, mostly with acute pancreatitis and pancreatic trauma, 64 needed surgical interventions. The total mortality rate encountered was a meagre 3.5%.

CONCLUSION

Paediatric pancreatic disorders are not so infrequent; and a high index of suspicion aided by the newer modalities of investigation greatly helps in the appropriate and timely management.

A rare case of incidentally diagnosed primary papillary carcinoma of thyroglossal duct cyst

Thyroglossal duct cysts are the most common congenital abnormality of thyroid development. Seventy percent of thyroglossal duct cysts are diagnosed during childhood and 7% are diagnosed in adulthood. Less than 1% of these cases are malignant with most being papillary in nature. It is often diagnosed incidentally after surgical excision. Incidentally discovered, well-differentiated thyroid carcinoma of the thyroglossal duct, in the presence of a clinically and radiologically normal thyroid gland, can be managed adequately by the Sistrunk operation. We present a rare case of primary papillary carcinoma of thyroglossal duct cyst, with normal thyroid gland, in a 28-year-old female that was diagnosed incidentally on histopathological examination. A Sistrunk procedure was performed on the patient to remove the thyroglossal duct cyst and patient is doing well at regular follow up.

Epidemiological and socio-cultural study of burn patients in m. y. hospital, indore, india

Background: developing countries have a high incidence of burn injuries, creating a formidable public health problem. the exact number of cases is difficult to determine: however in a country like india, with a population of over 1 billion, we would estimate 700,000 to 800,000 burn admissions annually. objective: the study was done to investigate the epidemiology of various causations and their outcomes in terms of morbidity and mortality. also, the effect of social stigma and cultural issues associated with burns on the victim and his family was assessed.Materials and methods: All burn cases (n=412) admitted to the burns unit of m. y. hospital, indore over a period of one year (2005-2006) were investigated. the data regarding sex, age predisposition, geographical origin, mode and nature of injury were obtained by questionnaire-interview with the patient themselves. clinical assessment was done in the form of depth and extent of injury and complications. in case of mortality, again various factors like age, sex and cause of death were analyzed. the data was analyzed by spss 11.0 version. the interrelationship between various factors was studied using multivariate logistic regression analysis.Results: Burns were found more commonly in middle-aged groups. the incidence was more in females as an absolute number (70.3%) as well as when stratified by age. most burns were domestic, with cooking being the most prevalent activity. flame (80.3%) was the most common agent. most of the cases of burn were accidental (67.7%). moreover, the patients had third degree burn that leads to more mortality in our circumstances. death occurred in more than one-half (62.3%) of cases with septicaemia and disseminated intravascular coagulation (35.4%) as the leading causes. when using logistic regression analysis, the outcome of the burn injury was significantly associated with degree, depth, extent and mode of injury.Conclusion: This series provides an overview of the most important aspects of burn injuries for hospital and non-hospital healthcare workers. the majority of deep burns are accidental, seen in middle-aged housewives as a result of flame burns, and lead to death. so measures should be taken to provide proper education to prevent these accidents and ensure safety.

Isolated left lung aplasia with bronchial asthma

Congenital lung anomalies are categorised as pulmonary agenesis, aplasia and hypoplasia with distinct clinical implications. An 8-year-old boy was referred for an opaque left hemithorax for which he had received antituberculous therapy. A detailed evaluation including flowing contrast computed tomography of the thorax and fiberoptic bronchoscopy led to a diagnosis of left lung aplasia. He also had wheezing dyspnea, which was confirmed as bronchial asthma. Congenital lung defects with associated asthma was reported only twice till date. A high index of suspicion is required to recognise such a patient.

Gossypiboma: its laparoscopic diagnosis and removal

Retained surgical sponges are an under-reported occurrence. Clinical presentation may be acute or subacute, and may follow months or even years after surgery. We report on a case in which laparoscopy was used to both diagnose and treat a retained surgical sponge.

The role of hyperosmolal food in the development of atherosclerosis

Hyperosmolality of ingested food causes excessive thermogenesis in humans. And when this heat does not find a way to dissipate or expelled from body it causes the blood circulatory system to build an insulator wall by depositing fat in aorta resulting in atherosclerosis. The mechanism of excessive thermogenesis is presently unknown. It seems that the hyperosmolal food stimulates intestinal osmoreceptors and raises plasma osmolality. However, the dissipation of this heat is less likely to occur in obese people than skinny people because there is an extra layer of fat in obese people. In addition, the climatic conditions do not affect the development of atherosclerosis. Therefore, hyperosmolality of ingested food is the primary factor in the development of atherosclerosis and obesity is only secondary. In addition, the ingestion of fat has practically no effect on the development of atherosclerosis because it does not cause thermogenesis like amino acids, sugars, and NaCl do. Thus, both skinny as well as obese people are at risk of developing atherosclerosis if they habitually consume hyperosmolal foods irrespective of what part of the world they live in.

Sub-surface investigations on deep saline groundwater of Charnockite rock formation, Kalpakkam, India

Investigations on geohydrological aspects of coastal aquifer are important in order to understand the mechanism of ground water salinisation. The present study describes the salinity variations of ground water in deep boreholes drilled in Charnockite rock formation of Kalpakkam, on the eastern coast of India. Water samples collected up to 600m depth were analyzed for salinity variation. It is noticed that in one of the boreholes, (borehole K1), the salinity level is found to be 74 parts per thousand (ppt) at 400 m depth. Influence of surface saline water bodies viz., sea (26-28.5 ppt), backwaters (27-30 pt) and Buckingham canal (27-32 ppt) as the possible sources of recharge of fresh waters through joint and fracture system of the rock are discussed in this paper. Studies would assist in understanding the geohydrological characteristics of deep geological formation.

Extraction and purification of cephalosporin antibiotics

The biologically active natural and semisynthetic cephalosporin antibiotics require proper methods of extraction and purification for their isolation and subsequent pharmacological studies. This article reviews the various methods useful for extraction and purification of individual compounds as well as the enzymes involved in their biosynthesis. Applicability of the methods for downstream processing of the spent medium has been critically analysed. Adsorption chromatography, particularly with reverse phase materials, in combination with membrane separation is the most successful technique for extraction as well as purification of most of the enzymes and individual compounds. Techniques such as reactive extraction in liquid membrane, non-dispersive extraction in hollow fiber membrane and aqueous two-phase extraction are likely to emerge in new generation processes. Finally, some aspects of process design and scale-up have been discussed, highlighting the research needs of pragmatic importance.

Sequential MTX-5 FU chemotherapy in pallination of advanced cancer cervix

Twenty four patients with advanced cancer of cervix were submitted to sequential chemotherapy 5FU and MTX. The response rate was 85% in stage III and 50% in stage IV. Overall response rate was 75%. Patients who had not received radiotherapy earlier responded better than those who had received it earlier. This easy and economical modality has importance in view of late reporting and advanced stage of disease encountered in our set up.

Computed tomography in spinal tuberculosis

Exhaustive clinicoradiologic and computed tomographic (CT) analysis of 114 cases of spinal tuberculosis seen between January 1983 and January 1989 is presented. The mechanisms of the spinal involvement are reviewed. CT helped to diagnose cases of spinal tuberculosis in their initial stages. Inaccessible fixed areas of spine were seen with ease on axial sections of CT. The extent and anatomic depiction of soft-tissue involvement as depicted on CT helps surgeons choose the appropriate surgical approach, which may affect future spinal stability.

Pulmonary alveolar microlithiasis with pleural calcification and nephrolithiasis

A case of pulmonary alveolar microlithiasis (PAM) with pleural calcification and nephrolithiasis is reported. The significance of peripheral white lines, a rarely reported observation on chest roentgenogram in PAM, is discussed. Extrapulmonary calcification in multiple sites raises the possibility of PAM being a systemic disorder.

Computed tomography of lipoma of corpus callosum and choroid plexus lipoma: report of two cases

Lipoma of corpus callosum and choroid plexus lipoma are rare developmental anomalies arising as a result of maldifferentiation of primitive meningeal tissue. Two cases are reported along with a brief review of literature. The first case presented with chronic headache, and a large lipoma of corpus callosum associated with choroid plexus lipoma was discovered. The second case had no symptoms before the discovery of corpus callosal lipoma on computed tomography, which was done for a head injury. None of the lipomas showed any calcification.

Role of computed tomography in staging of renal cell carcinoma

Accurate pre-operative staging of renal cell carcinoma is necessary to determine the surgical approach and prognosis. The advent of computed tomography has brought about a remarkable improvement in accuracy of pre-operative staging in such cases by non-invasive means. The role of computed tomography in staging of renal cell carcinoma has been evaluated in 28 cases and correlated with clinical and surgical findings.

Primary mediastinal echinococcosis

Computed tomography findings with surgical details are presented in a case of hydatid cyst of posterior mediastinum, a rare site of involvement in echinococcosis infestation. The computed tomography appearance of posterior mediastinal echinococcosis is quite characteristic and can be readily distinguished from other cystic lesions of the mediastinum. Computed tomography provides additional information regarding the involvement of neighboring structures. In this case, computed tomography detected involvement of the descending aorta.

On the mechanism of hypocholesterolemic action of amphotericin B in rat

The transient hypocholesterolemia phenomenon observed in rats, injected i.v. with amphotericin B (1.5 mg/kg/day) for three weeks, was investigated by in vitro [14C] acetate incorporation into the liver cholesterol. The incorporation of acetate in liver slices of treated animals increased more than two-fold (p less than 0.02) when compared with controls.When amphotericin B was added in vitro to liver slices of control rats, the incorporation of acetate into cholesterol decreased to about 65% of that observed with the corresponding controls (p less than 0.01). The results are consistent with the hypothesis that initially amphotericin B causes inhibition of de novo cholesterol synthesis resulting in hypocholesterolemia which disappears on continued treatment possibly due to compensatory increased rate of cholesterol biosynthesis.

Fractionation of serum cholesterol: a critique

A procedure for fractionation of serum cholesterol is developed by employing digitonin for the precipitation of free cholesterol in isopropanol. This method is based on the ferric acetate color reaction which is unaffected by traces of digitonin. It is influenced only negligibly by the presence of stanols in serum and is shown to be equally chromogenic with respect to both free and ester forms of cholesterol. The proposed procedure shows a three-fold improvement in precision (3.1 percent coefficient of variation [CV]) compared to that of the procedure by Leffler and McDougald (10.5 percent C.V.) which is based on the ferric chloride color reaction. The proposed free cholestrol procedure showed a mean recovery of 99.5% percent (98.1 to 102.5 percent) when cholesterol in 40 to 200 mg per dl concentrations was added to serum. The analytical performance of the proposed fractionation of serum cholesterol is critically reviewed with respect to its potential application in the diagnosis of liver diseases and in basic or experimental research.
