Aboveground and Soil Carbon Stock of Teak Plantations under Varied Rainfall Regimes

Aims: Forest plantations are considered to be the most effective approach to reducing the atmosphere's rising carbon dioxide levels. The variation in the carbon stock under important plantation species and the heterogeneity across climatic regimes, however, are urgently needed.Place and Methodology: Research was conducted on seven-year-old teak plantations in Karnataka, India, to determine the above-ground and soil carbon sequestration potential of teak plantations under various rainfall regimes.Results: The teak plantations under high rainfall zone (RFZ) accumulated maximum above-ground biomass revealing the positive effect of rainfall the productivity. This was reflected in the total above-ground carbon sequestration of the plantations leading to maximum carbon storage under the high RFZ followed by medium and low RFZ. Further, the variation of the SOC along the soil depth was evident in the present study.Conclusion: According to the findings, rainfall significantly impacted above-ground carbon sequestration and SOC, with high rainfall leading to the greatest sequestration. The climate sensitivity of carbon sequestration demands elaborate studies to improve carbon storage in the plantations in future climate change scenarios.

Comparative Evaluation of two Polishing Systems on the Surface Texture of an aesthetic material (nano-composite): A Profilometric Study.

Composites have revolutionized the concept in asthetic dentistry. Proper finishing and polishing of composites are important aspects of clinical restorative procedures that enhance both asthetics and the longevity of the restoration. A number of finishing and polishing devices are available, but to decide the efficacy of various materials is still a challenge to the dentists or clinicians. Hence the study was undertaken to determine the effectiveness of two polishing systems Sof-Lex and PoGo on Filtek Z350 by evaluating surface roughness using a Profilometer. The study concluded that Sof-Lex is a better polishing system than PoGo.

Sublingual traumatic ulceration due to neonatal teeth (Riga-Fede disease).

The term Riga-Fede disease has been used historically to describe traumatic ulceration that occurs on the ventral surface of tongue in neonates and infants. It is most often associated with natal and neonatal teeth in newborns. A case of Riga-Fede disease is presented.

Central giant cell granuloma in child: a case report.

The central giant cell granuloma or CGCG is a benign intraosseous lesion of the jaw. It is found predominantly in children and young adults. A case of 10 year old male child with CGCG in mandible is presented.

Tooth fragment reattachment--an esthetic alternative: report of a case.

Trauma to the anterior teeth is relatively common among children and teenagers. Reattachment of a fractured fragment to the remaining tooth can provide better and long lasting esthetics, improved function, a positive psychological response and is a faster and less complicated procedure. This article discusses fragment reattachment technique and presents clinical case of coronal fracture involving enamel and dentin.

Acute idiopathic thrombocytopenic purpura in childhood: a case report.

Acute thrombocytopenic purpura is the most common of thrombocytopenias of the childhood. Clinical features include petechial lesions on oral mucosa, gingival bleeding and occasionally hemorrhage. A case of acute thrombocytopenic purpura is presented.

Dental maturity as an indicator of chronological age: radiographic evaluation of dental age in 6 to 13 years children of Belgaum using Demirjian methods.

The study was designed to determine dental age from orthopantomograph using Demirjian method and to investigate applicability of Demirjian method for estimation of chronological age in children of Belgaum. The sample for the study consisted of 197 subjects between 6-13 years of age. When Demirjian method was applied to Belgaum children, mean difference between true and assessed age for males showed overestimation of 0.14 years (51 days) and females showed overestimation of 0.04 years (15 days). Demirjian method showed high accuracy when applied to Belgaum children.

Papillon-Lefevre syndrome: a report of two cases.

Papillon-Lefevre Syndrome (PLS) is an inherited autosomal recessive disorder presenting with Palmar plantar Keratoderma and Juvenile Periodontitis leading to early loss of both the dentitions. Two cases of PLS in a family with a history of consanguineous descent are presented.

Red cell distribution width in the diagnosis of iron deficiency anemia.

OBJECTIVE: 1. To compare peripheral smear (PS) and Red cell distribution width (RDW) in diagnosis of Iron deficiency anemia (IDA) in various grades. 2. To study the changes in RDW and PS after therapy. METHODS: Children in the age group of six months to five years with microcytic (MCV<80fl) anemia (Hemoglobin <11 g%) were evaluated. Those who had received blood transfusion and /or were already on iron therapy were excluded. Evaluation included clinical examination, complete blood count (CBC), RDW estimation microscopic examination of peripheral smear, measurement of serum iron and transferrin saturation. Children with IDA were treated with oral iron for 8 weeks and PS, CBC including RDW were repeated. RESULT: Of the 100 children evaluated, 89 had IDA. 48% had mild, 42% had moderate and 10% had severe anemia. Transferrin saturation correlated with severity of anemia. Peripheral smear showed microcytosis and hypochromia in all cases with severe anemia, 61.5% and 22.5% of those with moderate and mild anemia respectively. RDW was suggestive of iron deficiency in 100%, 82.05% and 100% of patient with mild, moderate and severe anemia respectively. CONCLUSION: In the diagnosis of mild and moderate iron deficiency anemia, RDW had a higher sensitivity than PS. Red cell morphology, Hb, PCV and RDW showed significant improvement after iron-therapy.

Natal and neonatal teeth: a case report.

A case of natal and neonatal teeth in a 25 days old infant and its management is reported.

Menetrier's disease.

An 8-year-old girl presented with persistent vomiting, pain abdomen and generalized edema. Barium studies and gastroscopy suggested hypertrophic gastropathy. Histopathological examination pointed the diagnosis towards Menetrier's Disease. There was spontaneous remission and the child required only supportive therapy.

Mechanical ventilation of newborns: experience from a level II NICU.

OBJECTIVES: To analyse the indications, clinical profile, complications and outcome of the babies requiring mechanical ventilation. DESIGN: Retrospective study. SETTING: NICU of a teaching hospital. SUBJECTS: One hundred and twenty one neonates requiring assisted ventilation during three years. RESULTS: Of 121 babies 59(48.76%) survived. Hyaline membrane disease (HMD) was the commonest indication for ventilation followed by birth asphyxia, apnea of prematurity, meconium aspiration syndrome (MAS) and septicemia. Infants with HMD whose birth weight was more than 1.5 kg and those who required ventilation after 24 hours of birth had better outcome. Survival rates increased with increasing birth weight and gestational age. Prolonged ventilatory support was needed for HMD (mean 117.3 hr) and MAS (mean 82.6 hr). Pneumonia was the commonest complication, followed by sepsis, air leak syndromes and intracranial and pulmonary hemorrhage. CONCLUSIONS: Ventilatory facilities must be focussed for neonates weighing > 1000 g. Assisted ventilation may not be cost-effective in patients weighing < or = 1000 g and those with complex heart diseases and other congenital anomalies.

Salmonella typhimurium isolated from bacteraemia.

During a two year period, a total of 15 strains of S. typhimurium were isolated and analysed by phage typing. Of these, 13 were found untypable, while two strains belonged to phage 76 and 22. All the strains were sensitive to Gentamicin and Cephaloridine. All but one showed multiple drug resistance.
