Relative potential of rhizobium species to enhance the growth and yield attributes of cotton (Gossypium hirsutum L.)

Legumes compensate mineral fertilizer by fixing nitrogen due to the specialized structures i.e. nodules by Rhizobium species. Literature revealed that legumes fixed nitrogen due to Rhizobium inoculation from 50-300 kg NPK ha-1 year-1. Rhizobium besides nitrogen fixation, solubilized phosphates, produced growth hormones and due to its root colonizing ability improved the growth and yield of non-legumes also and performed as plant growth promoting rhizobacteria (PGPR). Study was conducted to assess the relative efficiency of Rhizobium species for the growth and yield of cotton. Different isolates of five species of Rhizobium species responsible for different nodule formation in legumes were assessed for the auxin biosynthesis potential as IAA equivalents and isolates having higher values for IAA equivalents were used for experimentation. Results revealed that isolates of Rhizobium species improved the growth and physiological parameters of cotton. Higher values were root/shoot length and mass were observed with Rhizobium species of berseem (Br5). Bacterial inoculation with isolate (Br5) produced 60.94, 64.40 g shoot/root mass that is 16.70 and 23.80 % higher than control and percent increase improvements of cotton shoot/root length with Br5 i.e. 18.3, 24.8 % higher than that of control. Higher values of IAA equivalents were observed in root/shoot content of cotton with isolate of Br5. Bacterial inoculation improved the plant height, boll weight, number of bolls plant-1 and seed cotton yield with Br5 inoculation. The chlorophyll content, photosynthetic rate, transpiration rate and photo active radiation were also higher in the inoculated treatments. Results of present study clearly demonstrated that different isolates of Rhizobium species improved the growth and yield parameters of cotton and thus Rhizobium sp can be effectively utilized as bacterial inoculants in non-legumes

Treatment outcomes of patients with tuberculosis in war affected region of Khyber Pakhtunkhwa, Pakistan

Background: Globally, tuberculosis (TB) remains the leading cause of death from a single infectious disease. TB treatment outcome is an important indicator for the effectiveness of a national TB control program. This study aimed to assess treatment outcomes of TB patients and its determinants in Batkhela, Khyber Pakhtunkhwa, Pakistan. Methods: A retrospective cohort study was designed using all TB patients who were enrolled at District Head Quarter (DHQ) Hospital Batkhela, Pakistan, from January 2011 to December 2014. A binary logistic regression models were used to identify factors associated with successful TB treatment outcomes defined as the sum of cure and completed treatment. Results: A total of 515 TB patients were registered, of which 237 (46%) were males and 278 (53.98%) females. Of all patients, 234 (45.44%) were cured and 210 (40.77%) completed treatment. The overall treatment success rate was 444 (86.21%). Age 0-20 years (adjusted odds ratio, AOR = 3.47; 95% confidence interval, CI) = 1.54-7.81; P = 0.003), smear-positive pulmonary TB (AOR) = 3.58; 95% CI = 1.89-6.78; P = < 0.001), treatment category (AOR = 4.71; 95% CI = 1.17-18.97; P = 0.029), and year of enrollment 2012 (AOR = 6.26; 95% CI = 2.52-15.59; P = < 0.001) were significantly associated with successful treatment outcome. Conclusions: The overall treatment success rate is satisfactory but still need to be improved to achieve the international targeted treatment outcome. Type of TB, age, treatment category, and year of enrollment were significantly associated with successful treatment outcomes

Psychosocial responses to disaster: An Asian perspective

The psychological and psychiatric impact of great natural disasters are beginning to be understood leading to new methods of prevention, intervention and mitigation. There is limited data from the Asian continent, however, which has been the location of some of the greatest disasters of recent times. In this paper, we outline the psychosocial intervention efforts from nine Asian nations when confronted with large-scale natural catastrophic events. These include reports from situations where local services have some capacity to respond as well as those where services are destroyed or overwhelmed. From this it is possible to draw some general principles of psychosocial disaster intervention: (1) Assessment of disaster, extant service systems and incoming resources. (2) Assessment of help-seeking pathways and cultural models of illness. (3) Facilitation and support for family reunion, identification of the dead and cultural and religious practices to address death and grief. (4) Foster and bolster community group activities where possible. (5) Psychosocial training of community, aid and health workers using a train the trainer model to promote case identification, psychoeducation and intervention, with specific emphasis on vulnerable groups, especially children. (6) Promote general community psychoeducation. (7) Train medical and health staff in basic psychiatric and psychological assessment and intervention for post-traumatic stress, mood and anxiety disorders. (8) Minimise risk factors for psychiatric morbidity such as displacement and loss of gainful activity. (9) Reshape mental health systems recognising the long-term psychiatric sequelae of disaster. The collective learnt experience from Asian natural disasters may be constructively used to plan strategies to respond appropriately to the psychosocial consequences of disaster both within Asia and in the rest of the world. © 2008.Suresh Sundram...Daya Somasundaram...et al
