Featured Issue: Ciência Florestal Vol.23 No.4

Today we are featuring vol.23 no.4 of Ciência Florestal.

Teak is a popular source of wood for commercial use, used for both indoor and outdoor furniture. Teak is grown in many parts of Asia such as Thailand, Indonesia and Myanmar. Brazil has also grown Teak trees since the 1970s. This issue of Ciência Florestal includes "Occurence and Pathogenicity of Meloidogyne javanica on Teak (Tectona grandis Linn. F.) Plants" by de Oliveira & da Silva. The article details the occurrence of the nematode Meloidogyne javanica on Teak plants (Tectona grandis) grown in Mato Grosso, Brazil. For the study, female larvae of the Meloidogyne javanica were extracted from the roots of Teak plants. The results indicated that teak is vulnerable to the nematode because of reproduction factor, and that the nematode is a pathogen to the Teak plant, as the Teak plants were found to have nutrient deficiency.

This issue also includes "Substrate for Production of Macacaúba (Platymiscium ulei Harms) Seedlings in the Autazes town, Amazonas State" by de Miranda et al. This article details the efficiency levels of different substrates on Macacaúba seedlings used in reforestation in Autazes, Amazonas State. Eight treatments of the substrate were administered in random blocks, and five replicates were tested. Some of the treatments included: cattle manure, lime, corrective phosphate, fertilizer with NPK, and lime + correction phosphate. The treatments were tested for 120 days, after which the following characteristics were evaluated: height of shoot, diameter of the neck, shoot, paroot and total dry matter, nutrient levels and amounts in shoot dry matter. The results indicated that all the treatments improved the soil of the seedlings, as more nutrients were found. The results also indicated that plants grown in cattle manure had higher nutrient absorption and growth rates. The study concludes that cattle manure could be the best treatment for the production of Macacaúba seedlings.

The importance of mental health and awareness of mental illness has taken a spotlight on the world stage. One article in this issue of Iranian Journal of Pediatrics, "Effectiveness of Cognitive-Behavioral Therapy in Decreasing Suicidal Ideation and Hopelessness of the Adolescents with Previous Suicidal Attempts" by Alavi et al., examines how Cognitive Behaviour Therapy (CBT) has affected a group of 30 young adults ages 12 to 18 who have been diagnosed with depression and have attempted suicide in the previous three months before the study was conducted. The group underwent a 12-week program of CBT and were evaluated by the Scale of Suicide Ideation, Beck's Hopelessness Inventory and Beck's Depression Inventory before and after the program. The results indicated that there was a significant difference between scores found before and after treatment. It was concluded that CBT is effective in reducing suicide ideation.

This issue also includes "Apparent Life-Threatening Events in Neonatal Period: Clinical Manifestations and Diagnostic Challenges in a Pediatric Referral Center" by Alavi et al. This article evaluates infants who experience episodes of Apparent Life-Threatening Events (ALTEs) in which they can experience apnea, colour change, altered muscle tone, choking and gagging. The study was conducted between June 2010 and May 2011. 18 infants who were treated at the Children's Medical Center in Tehran underwent physical exams and their medical histories were examined, as well as paraclinical findings. The study found that 50% of patients had previous ALTE episodes. Among common symptoms were cyanosis, which was experienced by 67% of patients, and apnea, which was experienced in 44% of patients. It was also found that no infants experienced recurring ALTEs at the follow-up exam. The study concludes that more attention should be paid to the underlying diseases of ALTEs.

Today we are featuring Memórias do Instituto Oswaldo Cruz vol.108 no.5. 

This issue includes "Polycystic echinococcosis in the state of Acre, Brazil: contribution to patient diagnosis, treatment and prognosis" by de Siquera et al., which examines the process of diagnosis and treatment for patients with Polycystic echinococcosis. The study started in 1999 and by 2009, included 60 patients. Patients were classified based on parasite lesions, neighbouring organ invasion and metastases, and were subsequently divided into three groups to receive either chemotherapy, surgical removal of the cysts or puncturing of the cysts using the PAIR method. The results indicated that surgical removal of the cysts could be the best method of treatment out of the three treatments described above, and that the PAIR method requires more research.

Also included in this issue is "Culicidae (Diptera) selection of humans, chickens and rabbits in three different environments in the province of Chaco, Argentina" by Stein et al. For this study, mosquitoes were collected by using chicken and rabbit bait during the period of June 2001 to May 2002. The incidence of mosquitoes biting the humans operating the traps was also collected. 49 species and 10 genera of mosquitoes were collected. The results indicated that Culex species were most attracted to chicken bait, while Wyeomyia species were most attracted to rabbit bait. Several species including Psorophora albigenu were most attracted to human bait.
