1. The age changes in carcass composition of female kids killed at birth, 9, 16, 25 and 30 lb. are described.2. The organs and tissues of the kids were weighed both wet and oven-dried, allowing the dry-matter percentages at different stages of growth to be calculated. The total dry-matter percentage for day-old kids averaged 26·5%, rising to a maximum of 40·5% at the 25 lb. stage. The greatest increase in dry-matter percentage was between birth and the 9 lb. stage, which was reached at approximately 1 month. This increase in dry matter is chiefly due to a steady rise in the dry-matter content of the muscular and skeletal tissues; from 20·2 to 25·4%, and from 34·3 to 59·6%, respectively, between birth and maturity.3. The various joints of the kid were weighed and recorded separately, and the changes in the proportions of the joints illustrated centripetal growth. At birth, the joints were present in the following proportions: thorax 30%; legs 40%; head 20%; pelvis 10%. As the kid developed, there was a marked increase in the proportion of thorax and pelvis, accompanied by a corresponding decrease in the proportion of the head and foreleg.

A laboratory breeding colony of R. l. lutreolus was used to obtain data on the growth in the length of head, hind foot, tail, head and body, and body weight during the first 130 days of life. The development of external body features was compared to that known for other Australian Rattus. The young are blind and naked at birth and are not fully furred until 13 days. Incisors are visible at day 8 (5-11) and erupt about day 12 (8-15) with the eyes opening at 17 days (15-18). Independence was achieved at about 25 days (23-30) with the first signs of reproductive maturity at about 60-70 days. Five stages of growth can be related to developmental features from teeth eruption to puberty and reproductive maturity. The onset of hearing (14-15) days appear to be as important in development as does the opening of the eyes. Body measurements show sigmoid relationships to a linear equivalence of weight (W*0.33), except for head and body length which is linear. R. l. lutreolus belongs to the fast-growing group in Australian murids. Measurements from laboratory-bred animals are in agreement with those for field animals, with head and body length the best single parameter for obtaining approximate ages.

Experimental study on the growth and development of saline and non-saline populations of Eclipta alba Hassk., planted on soils artificially salinized with water-soluble salts of sodium and a saturation extract of saline soil, revealed differences in their salt-adaptive capabilities. The relatively higher salt-adaptive capability of the saline population both at germination and subsequent stages of growth indicated ecophysiological differentiation within species due to salt stress.

Menarche is the first experience of menstruation would cause anxiety among teenagers, fear, discomfort, and affect the quality of life of teenage. This condition was caused by the taboo assumption to discuss menstruation with family and their environment. Therefore, this study was conducted to identify urban teenagers' readiness toward menarche. This study was conducted with the process of searching, collecting and analyzing articles. The search sources used were Cinahl, Scopus, Cochrane, Pubmed, and Cengage databases. The keywords used were menarche, readiness, and urban teenagers. The inclusion criteria used were 2013 - 2018 research articles, full text, and English articles. The exclusion criteria used was non-urban teenagers. According to the keyword was found 124 articles. After being selected based on the inclusion and exclusion criteria, 7 articles were analyzed. The result showed urban teenagers' readiness consisted of internal and external readiness. Internal readiness consists of age and knowledge. Internal readiness can affect self-acceptance, maturity of mind, and views on the stages of growth and development that are being faced. External readiness consists of social support. Social support for urban teenagers is useful to get information and attention when menarche. External readiness for urban teenagers was already good but lack of internal readiness. Therefore, counseling and health education related to menarche was needed starting from elementary school.Keywords: Menarche, readiness, urban teenager.

Beech mushrooms (Hypsizygus marmoreus) are largely relished for their characteristic earthy flavor, chewy-texture, and gustatory and nutritional properties in East Asian societies. Intriguingly, the aforementioned properties of beech mushroom can be subsumed under its elusive metabolome and subtle transcriptome regulating its various stages of growth and development. Herein, we carried out an integrated metabolomic and transcriptomic profiling for different sized beech mushrooms across spatial components (cap and stipe) to delineate their signature pathways. We observed that metabolite profiles and differentially expressed gene (DEGs) displayed marked synergy for specific signature pathways according to mushroom sizes. Notably, the amino acid, nucleotide, and terpenoid metabolism-related metabolites and genes were more abundant in small-sized mushrooms. On the other hand, the relative levels of carbohydrates and TCA intermediate metabolites as well as corresponding genes were linearly increased with mushroom size. However, the composition of flavor-related metabolites was varying in different sized beech mushrooms. Our study explores the signature pathways associated with growth, development, nutritional, functional and organoleptic properties of different sized beech mushrooms.
