Analysis of Renal Stones by FT-IR Spectroscopy: A Helpful, Simple and Accurate Tool | Chapter 02 | Emerging Research in Medical Sciences Vol. 3

Aims: To investigate, by infrared spectroscopy (FT-IR), the chemical composition of urinary calculi obtained from patients of Buenos Aires, Argentina. Duration of Study: The composition of the urinary calculi was evaluated in a retrospective study from March 1993 to December 2018. Methodology: Infrared spectra of the urinary calculi were recorded in a Bruker IFS-25 FT-IR, Bruker Alpha-T and in a Nicolet 380 FT-IR spectrophotometers. We included 542 urinary stones (331 from men and 211 from women). The samples were obtained by spontaneous passage, shockwave lithotripsy, ureteroscopy or percutaneous nephrolithotripsy. Results: Calcium oxalate (both in pure or mixed samples) was detected in 396 cases (73.06%). Anhydrous uric acid and struvite+apatite (7.56%) were both observed most frequently, followed by carbonate apatite + amorphous Ca-phosphate (2.58%) and cystine (2.03%). For some chemical compounds, a significant gender-related difference was found. Applying the seco...

Identification of the Essential Oils from Annona senégalensis Pers. Sous-espèce Oulotricha Le Thomas (Annonaceae) | Chapter 07 | Advances and Trends in Biotechnology and Genetics Vol. 3

Annona senegalensis Pers., Oulotricha Le Thomas subspecies (Annonaceae), is an evergreen shrub that is used for ethnomedicinal purposes and as a source of food. The chemical composition of the essential oils from leaves, stems bark, roots bark, epicarp and mesocarp of these plant, growing in Brazzaville (Congo), were analyzed by CG and CG-MS. These oils essentially contain sesquiterpenic compounds (58.3-97.7%), dominated by oxygenated sesquiterpenes (21.8-88.3%), with elemol (13.2-35.0%), β-and γ-eudesmols (3.7-58.3%) as characteristic components. The essential oils from roots and stems bark is distinguished by its high content in diterpenes (17.1 and 11.9% of the total), while the seeds presents a significant amounts of monoterpene hydrocarbons (25.8%) with α-pinene (6.2%) and β-phellandrene (11.5%) as major components accompanied by two oxygenated monoterpenes : bornyle acetate (4.5%) and smallest of 1,8-cineole. However, in the epicarp oil, the presence of about 5.8% of oxygenated...

Amylase Rich Malted Foods on the Nutritional Status of Pregnant Women, Lactating Women and Preschool Children in Lepakshi Mandal of Ananthapur District, Andhra Pradesh, India | Chapter 01 | Theory and Applications of Microbiology and Biotechnology Vol. 2

Two types of Ready to Use Amylase rich malted mixes (Ragi / Wheat in combination with green gram) were formulated and suitable products namely laddu, roti, kheer and porridge were prepared using formulated malted mixes . The incorporation of malted green gram mix and skimmed milk powder to the wheat malted mix and ragi malted mix helped to improve nutritive value of the malted mixes, specially   protein, energy, iron, calcium and ‘B’ complex vitamins . After collecting baseline information of the identified villages of 3 mandals, Lepakashimandal was selected for implementing the study based on the availability of more subjects of low socio economic group with majority of families belonging to schedule caste and schedule tribes. ARMMs of two types (ragi/wheat) were formulated. Information of preschool children (400), pregnant women (100) and lactating women (100) was collected. Anthropometric, hemoglobin, clinical and morbidity assessments were carried out before & after supp...
