Physical and verbal aggression is a significant problem for some individuals with mild intellectual disabilities who reside in the community. We assessed the effectiveness of a mindfulness-based procedure, Meditation on the Soles of the Feet , to control both physical and verbal aggression. The design was a two-group (experimental and waiting list control) randomized controlled trial with four 12-week phases. A total of 57 individuals were referred to the trial, with 34 eligible for random assignment to the experimental and control conditions. Results showed a significant reduction in physical and verbal aggression commensurate with mindfulness-based training, when compared to the waiting list control condition. Similar reductions in physical and verbal aggression were evident when the same training was introduced in the control condition. The results demonstrate the effectiveness of the mindfulness-based procedure for assisting individuals with mild intellectual disabilities to control their physical and verbal aggression.

Because of large-scale destruction of natural areas due to mining operations, a restoration strategy is needed as a part of the overall mining management plan. In restoration, emphasis is given first to build soil organic matter, nutrients and vegetation cover to accelerate natural recovery process. Tree plantations can be used as a tool for mine spoil restoration as they have ability to restore soil fertility and ameliorate microclimatic conditions. We discuss here various approaches of ecosystem restoration on mine spoil, criteria for the selection of plantation species and future research needs in this regard.

A series of experiments was conducted on the rehabilitation of mine spoil in a dry tropical region of India for determining the suitability of tree species for plantation, growth performance of selected indigenous species in monoculture and impact of the plantations on the restoration of biological fertility of soil. All of the 17 indigenous species examined could grow in the mine spoil and the growth of a majority of them could be improved by amending the mine spoil with NPK fertilizer. Direct seeding showed greatest height of Zizyphus jujuba and Pongamia pinnata on flat surface, and of Azadirachta indica on slope. In terms of diameter, Syzygium cumini performed best on flat surface and Terminalia arjuna on slope. Total biomass in plantations of selected native tree species on mine spoil at 5-yr age varied from 7.2 to 74.7 t ha-1, being minimum for Shorea robusta and maximum for Dendrocalamus strictus. Total net production ranged from 3.5 (for Shorea robusta) to 32.0 t ha-1 yr-1 (for Dendrocalamus strictus), respectively. Microbial biomass in the redeveloping soil was lower compared to that in natural forest soil but immobilization of soil C in microbial biomass was greater in the mine spoil than in the natural forest. The study indicated that net primary production of the plantations was a function of the amount of foliage, soil C was a function of the amount of litter fall and biomass C was a function of soil C. Plantation of trees significantly accelerated the soil redevelopment process on the mine spoil.

Isolated choledochal cysts involving the cystic duct are rare. We present a case of a choledochal cyst involving only the proximal cystic duct, and discuss the taxonomic and therapeutic challenges. There is a need for a clearly defined classification system for these cysts as they may be categorised as either type II or type VI cysts. The optimal treatment remains debatable, with some authors recommending a bilioenteric reconstruction owing to the wide cystic duct–bile duct junction. However, we suggest that a cholecystectomy should be performed with examination of the specimen and frozen section in case of any abnormality rather than upfront bile duct excision. In addition, given the rarity of this condition and the paucity of long-term data, we recommend meticulous follow-up for development of any malignancy.

Lithium tetraborate based phosphor (Li 2 B 4 O 7 :Cu, Ag, P) is a suitable material for thermoluminescence dosimetery. It is prepared at Thermoluminescence Dosimetry Laboratory, Thoubal College, Manipur and has been analyzed using recently formulated simplified General one Trap equation to determine the trapping parameters. This new simplified equation helps in finding the key trapping parameters E , s , N , γ and α , which is not possible with the well known kinetic order formalism. From the analysis, it is found that activation energy of the phosphor is in the range 0.80–1.14 eV and frequency factor is ~10 8 –10 10  s −1 .

Phellinus Quel. is a member of family Hymenochaetaceae of the order Hymenochaetales. This genus comprises wood-inhabiting, saprophytic and parasitic species. Species of Phellinus sensu lato are known to have large host range and cause white rot of various types to live standing or dead trees from all over the world. The current study is based on a thorough study of literature to document the host range of Phellinus species from India. The study indicated that one hundred and seventy four plant species from 51 families are found to be infected by Phellinus species. The families found to be the most affected are Fabaceae, Combretaceae, Meliaceae, Dipterocarpaceae, Anacardiaceae, Myrtaceae, Meliaceae, Lauraceae, Fagaceae, Rosaceae.  Many plant (tree) species are affected by Phellinus; this establishes it as a potential pathogen and wood decay fungi. The present study also reports Phellinus from almost all over India and every climatic zones. This indicated the high tolerance and acclimatization of Phellinus towards diverse climatic conditions. The most affected host is Artocarpus followed by Terminalia and Acacia. Although the study reports Phellinus from diverse climatic zones of India, the most affected families and genera are from moist tropical conditions. This indicates that Phellinus has vigorous activity in warm and moist areas and affects diverse plant/tree species in these areas like Maharashtra and Kerala. The states like Uttar Pradesh, Bihar, Jharkhand, Odisha, Rajasthan, Karnataka, Andhra Pradesh, Telengana, Union Territories, Manipur, Mizoram and Nagaland are still left to be explored. The present study has key significance in biodiversity, medicinal as well as the pathogenic study of Phellinus. It provides an overall host range of genus Phellinus, confirming its vast host diversity. The information could further be used in disease, biodiversity and plant pathological assessments.

Exotic plants can potentially modify ecosystem functions like cycling of nutrients by adjusting their decomposition rates. However, these effects are largely unknown for urban ecosystems, though they act as reservoirs of exotic plants. The present study evaluated the decomposition rates of five native and five exotic (three invasive and two non-invasive) species by conducting the litter bag experiment. Our study, however, did not find any significant differences in overall decomposition rates of native and exotic species but decomposition rates were strongly correlated with initial chemical quality of the litter. Further, litter carbon, lignin to nitrogen ratio and carbon to nitrogen ratio seemed to be good predictors for decomposition rates in this study. Interestingly, invasive exotic species had higher decomposition rate while non-invasive exotic species showed a slower rate as compared to the native species. In conclusion, our study indicates that invasive exotic plants try to maintain a higher chemical quality of litter than native and non-invasive exotic species which promotes their rapid decomposition. Thus, the better chemical quality of litter may facilitate the naturalisation and invasion of exotic plants irrespective of their origin.

Primary malignant melanoma of the gastrointestinal tract is extremely rare. A 35-year-old man presented with complaints of abdominal pain and weight loss. Contrast enhanced computed tomography showed a large mass involving the duodenum and the superior mesenteric vessels. Upper gastrointestinal endoscopy demonstrated a large, friable mass along the duodenal wall and biopsy was suggestive of malignant melanoma. A detailed physical examination and whole body imaging (positron emission tomography and computed tomography) did not reveal any other lesion. The patient underwent a pancreaticoduodenectomy with segmental resection and anastomosis of the superior mesenteric vein as well as a segmental colectomy. His postoperative recovery was uneventful. The histopathology of the operative specimen showed a malignant amelanotic melanoma arising from the duodenum with lymph nodal involvement. He received oral temozolomide. However, he developed liver metastasis at six months and again at ten months, which was managed with radiofrequency ablation both times. He is doing well at 32 months of follow-up review. Multimodality treatment including surgery, adjuvant chemotherapy and salvage therapy appears to be a promising tool for achieving long-term survival in such patients.

Cotton cultivation has made rapid strides in India since the introduction of Bt cotton, which provided effective protection against its major pest, Helicoverpa armigera and other bollworms. The presence of alternate host crops for cotton bollworms targeted by Bt cotton play a key role in resistance evolution to the in planta expressed Bt proteins. Several host crops for H. armigera such as pigeonpea, sorghum, tomato, chilli, sunflower and corn are cultivated alongside Bt cotton. Change detection in the extent of cotton and alternate host crops of cotton bollworm was conducted using IRS LISS-III data in Punjab, Haryana, Rajasthan, Gujarat, Maharashtra, Andhra Pradesh and Karnataka states. The changes in the extent of cotton and host crops were monitored using multi-temporal data of 2002, 2004 and 2008. The results indicated that Bt cotton (Hirsutum) has almost completely replaced the traditional Indian cotton (Gossypium arborium). Several alternate host crops of H. armigera were grown along with cotton. Pigeonpea was the major host crop in almost all the locations. Chilies dominated in Andhra Pradesh, sunflower in Karnataka and corn in Gujarat. These host crops serve as ‘natural’ refuge of H. armigera and possibly, for this reason this pest has not evolved resistance to the Bt expressed by Bollgard II even after 16 seasons of intensive cultivation; whereas the pink bollworm, a monophagous cotton bollworm, had developed resistance to Cry1Ac in 2009 and to Cry1Ac and Cry2Ab in 2015.

Smoking is a major public health issue; it is a risk factor for numerous health conditions. Tobacco use is the primary preventable cause of disability and disease in many countries, including the USA, but many smokers find it difficult to quit smoking without specific interventions. We evaluated the effectiveness of a mindfulness-based smoking cessation program with three men with mild intellectual disabilities who had been smokers for many years and who had previously failed to quit smoking with other interventions. The mindfulness-based smoking cessation program included basic concentration meditation, daily intention, mindful observation of thoughts, and Meditation on the Soles of the Feet . A changing criterion analysis showed that the men were able to fade their cigarette smoking from a daily average of 28.4, 34.8, and 13.8 at baseline to 0 within 111, 165, and 77 days, respectively, and maintain this for a year. Follow-up data, collected every 3 months following the maintenance period, showed that they were able to abstain from smoking for 3 years. Our study suggests that this mindfulness-based smoking cessation program may be effective with other individuals with mild intellectual disabilities.
