Carbon stocks and dynamics of different land uses on the Cerrado agricultural frontier.

The largest and most dynamic agricultural frontier in Brazil is known as MATOPIBA, an area that covers part of the Cerrado biome. Within this region, Western Bahia stands out as a large producer of soy and cotton. There are no studies that quantify carbon stocks for different land uses and land cover types in Western Bahia, which hinders comprehension of the role of agricultural expansion in carbon dynamics and the development of sustainable agriculture policies.

Hepatitis B prophylaxis in newborns: A cross-sectional study of 7-year attendance in a public hospital of Brazil.

Background: Children with vertically transmitted hepatitis B virus develop chronic infection up to 90% of the time. This study aimed to verify the prevalence of hepatitis B surface antigen (HBsAg) in pregnant patients treated in a Brazilian public hospital and analyze the prophylactic measures in newborns.

Methods: A cross-sectional study was conducted by collcting data in the electronic charts of patients who attended the obstetric and maternity departments, from January 1, 2010, to December 31, 2016, and evaluating the results of pregnant women's HBsAg, prophylaxis in newborns, and clinical follow-up.

Analysis of the stomatognathic system of children according orthodontic treatment needs.

Purpose: The present study evaluated electromyographic activity (EMG), masticatory performance, and tongue strength in children without and with orthodontic treatment needs.

Patients And Methods: A total of 90 children were screened and divided into the following groups: Group I (no treatment needed; mean age: 8.00 ± 0.

Influence of anthropometry, TMD, and sex on molar bite force in adolescents with and without orthodontic needs.

Purpose: Bite force has been studied as representative of functional indices of mastication and its value may have diagnostic significance in disorders of the musculoskeletal system of facial bones. This study aimed to evaluate bite force in adolescents with and without orthodontic needs considering presence of temporomandibular disorders (TMD) as well as anthropometry: craniofacial dimensions and body mass index (BMI).

Methods: A total of 80 subjects were screened (61 females, 19 males; 18 ± 3 years old).

Masticatory muscle activity evaluation by electromyography in subjects with zygomatic implants.

Background: Zygomatic implants are an alternative treatment in the rehabilitation of atrophic maxilla to promote stability in the stomatognathic system. The aim of this study was to compare the electromyographic (EMG) activity of masseter and temporalis muscles in controls and in individuals with complete implant-supported dentures anchored in the zygomatic bone.

Materials And Methods: Fifty-four volunteers of both genders (mean age 52.
