Objective: This study aimed to examine the effect of vitrification on apoptosis and survival in human preantral follicles after thawing. Methods: This experimental study was conducted at an acute tertiary care hospital from March 2012 to April 2013. Ovaries were sliced into 5 × 5 × 1-mm pieces and divided into the following three groups: preantral follicle isolation, ovarian tissue vitrification-warming followed by follicle isolation, and immunohistochemistry of fresh ovarian tissue. For statistical analyses, the Student t-test, chi-square test, Kruskal-Wallis test, and Kaplan-Meier survival analysis were used. Results: A total of 161 preantral follicles (70% secondary) were collected from ovarian cortex tissue of six women between 30 and 37 years of age who underwent oophorectomy due to cervical cancer or breast cancer. There were no significant differences in the follicular morphology of fresh preantral follicles and vitrified follicles after thawing. The mean Fas ligand (FasL) mRNA expression level was 0.43 ± 0.20 (relative to β-actin) in fresh preantral follicles versus 0.51 ± 0.20 in vitrified follicles (p= 0.22). The mean caspase-3 mRNA expression level in fresh preantral follicles was 0.56 ± 0.49 vs. 0.27 ± 0.21 in vitrified follicles (p= 0.233). One vitrified-thawed secondary follicle grew and developed to an antral follicle within 6 days of culture. Conclusion: Vitrification did not affect preantral follicle morphology or mRNA expression of the apoptosis markers FasL and caspase-3. Further studies are required to establish whether vitrification affects the outcomes of in vitro culture and the maturation of preantral follicles.

Background: Complementary alternative medicine (CAM) use in children with cancer is widespread. Health-care providers (HCP) need to acknowledge and address this need. This study explored and compared perspectives on CAM of HCP and parents of young patients with cancer in Indonesia. Materials and Methods: We conducted a cross-sectional study using semi-structured questionnaires in HCP and parents of childhood cancer patients at an Indonesian academic hospital. Results: A total of 351 respondents participated: 175 HCP (response rate 80%) and 176 parents (response rate 80%). Parents were more likely than HCP to think that chemotherapy can cure cancer (80% compared to 69%, P=0.013). Nearly half of all parents (46%) and HCP (45%) doubted whether CAM can cure cancer. Parents were more likely than HCP to think that CAM can be helpful in childhood cancer treatment (54% compared to 35%, P=0.003). The most recommended CAM by HCP was self-prayer (93%). Reasons for recommending CAM were: hope for improvement of the child's condition (48%), patient wants to stop treatment (42%). Most discouraged CAM by HCP was by old-smart people (70%), the reasons being: lack of evidence for usefulness (77%), lack of CAM knowledge (75%). The proportion thinking that patients were unlikely to raise the CAM topic if they perceived that doctors were skeptical was higher in parents than in HCP (52% versus 1%) (P<0.001). Most HCP (71%) and parents (77%) acknowledged that their knowledge about safety and efficacy of CAM was inadequate (P=ns). The proportion that wanted to learn or read more about CAM was higher among parents than HCP (48% compared to 31%, P=0.002). Conclusions: HCP and parents have different perspectives on CAM use in children with cancer. HCP should enhance their CAM knowledge and encourage open communication about CAM with parents. If doctors' skepticism is perceived, parents are unlikely to raise CAM as a topic.

A digestibility study was conducted to evaluate the effects of supplementing mulberry foliage and urea rice-bran as a source of fermentable energy and protein to 12 sheep fed diets based on urea-treated rice straw (TRS). The three dietary treatments were: T1, TRS with mulberry; T2, TRS with 50% mulberry replaced with rice bran and urea; and T3, TRS with rice bran and urea. The study was arranged in a completely randomized design with four replications for each treatment. The sheep were fed one of the three diets and the supplements were offered at 1.2% of the body weight (BW) and the TRS was provided ad libitum. There were no differences (p>0.05) among the three treatment groups with respect to dry matter (DM) intake ($76.8{\pm}4.2g/kg\;BW^{0.75}$) and DM, organic matter (OM), and crude protein (CP) digestibility ($55.3{\pm}1.22$; $69.9{\pm}0.85$; $46.3{\pm}1.65%$ respectively for DM, OM, and CP). The digestibility of fiber (neutral detergent fiber [NDF] and acid detergent fiber) was significantly lower (p<0.05) for T3 (46.2 and 46.6 respectively) compared to T1 (55.8 and 53.7 respectively) and T2 (54.1 and 52.8 respectively). Nitrogen (N) intake by sheep on diet T3 was significantly (p<0.05) higher than sheep fed diet T1. However, N balance did not differ among the three diets ($3.0{\pm}0.32g/d$). In contrast, the rumen ammonia ($NH_3-N$) concentrations in sheep fed T2 and T3 were significantly (p<0.05) higher than in sheep fed T1. The $NH_3-N$ concentrations for all three diets were above the critical value required for optimum rumen microbial growth and synthesis. Total volatile fatty acid concentrations were highest (p<0.05) in T1 (120.3 mM), whilst the molar proportion of propionic acid was highest in T3 (36.9%). However, the microbial N supply in sheep fed T1 and T3 was similar but was significantly (p<0.05) higher than for sheep fed T2. It was concluded that mulberry foliage is a potential supplement of fermentable energy and protein for sheep fed TRS based diet. The suggested level of supplementation is 1.2% of BW or 32% of the total diet since it resulted in similar effects on the intake of DM, OM, and NDF, digestibility of DM, OM, and CP, N utilization and microbial supply when compared to rice bran and urea supplementation.

Skin aging is a complex biological process due to intrinsic and extrinsic factors. Free radical oxidative is one of extrinsic factors that induce activation of collagenase, elastase and hyaluronidase. Natural product from plants has been used as antioxidant and antiaging. This study aimed to evaluate antioxidant and antiaging properties of Hibiscus sabdariffa extract (HSE) and its compounds including myricetin, ascorbic acid, and ${\beta}$ carotene. The phytochemical of H. sabdariffa was determined using modified Farnsworth method and presence of phenols, flavonoids and tannins were in moderate content, whereas triterpenoids and alkaloids were in low content. Total phenolic content performed using Folin-Ciocalteu method, was $23.85{\mu}gGAE/mg$. Quantitative analysis of myricetin, ${\beta}-carotene$, and ascorbic acid of HSE was performed with Ultra-High Performance Liquid Chromatography (UHPLC) that shows $78.23{\mu}g/mg$ myricetin, $0.034{\mu}g/mg$ ${\beta}-carotene$, whilst ascorbic acid was not detected. HSE has lower activity on DPPH ($IC_{50}=195.73{\mu}g/mL$) compared to ${\beta}-carotene$, the lowest in ABTS assay ($IC_{50}=74.58{\mu}g/mL$) and low activity in FRAP assay ($46.24{\mu}MFe(II)/{\mu}g\;$) compared to myricetin, ${\beta}-carotene$. Antiaging was measured through inhibitory activity of collagenase, elastase, and hyaluronidase. HSE had weakest collagenase inhibitory activity ($IC_{50}=750.33{\mu}g/mL$), elastase inhibitory activity ($103.83{\mu}g/mL$), hyaluronidase inhibitory activity ($IC_{50}=619.43{\mu}g/mL$) compared to myricetin, ${\beta}-carotene$, and ascorbic acid. HSE contain higher myricetin compared to ${\beta}-carotene$. HSE has moderate antioxidants and lowest antiaging activities. Myricetin is the most active both antioxidant and antiaging activities.

Eucalyptus pellita F. Muell is one of pulp woods that is being developed through breeding plantation programs in Indonesia. The research aimed at exploring the chemical and morphological characteristics of fiber, and to determine the rank of plus trees from 4 provenances based on the suitability for pulps. The materials included the plus trees of E. pellita (9 years) from the 2nd generation of progeny tests in Pelaihari, South Borneo. Wood properties under investigation included the chemical properties and morphological fiber characteristics (fiber dimensions and its derived properties). In the present study, data were analyzed using descriptive statistic, Analytic Hierarchy Process (AHP) and Pearson's correlation. Results showed that the chemical properties of E. pellita, i.e. the contents of ethanol-toluene extractives, hot water soluble extractives, holocellulose, alphacelullose, and lignin were $3.08{\pm}1.00%$, $1.41{\pm}0.38%$, $75.26{\pm}2.58%$, $49.02{\pm}2.88%$, and $29.49{\pm}1.86%$, respectively. The average values of wood fiber morphology were $1.02{\pm}0.08$ mm (fiber length), $13.25{\pm}1.64{\mu}m$ (fiber diameter), of $6.94{\pm}1.70{\mu}m$ (lumen diameter), $3.15{\pm}0.52{\mu}m$ (fiber wall thickness), $0.97{\pm}0.30$ (Runkel ratio), $0.57{\pm}0.10$ (Luce's shape factor), $78.21{\pm}10.34$ (slenderness ratio) and $130.91{\pm}33.77{\times}10^3{\mu}m^3$ (solids factor). The AHP scoring rank indicated that the best individuals were 28.4.3.28 (Kiriwo Utara), 12.1.5.28 (North Kiriwo), 19.11.5.45 (Serisa Village), 3.8.4.9 (South Kiriwo), and 6.6.3.15 (South Kiriwo). Pearson correlation analysis showed significant correlations between the levels of fiber length with alpha-cellulose content (r = 0.39) as well as the fiber length with ethanol-toluene extractive contents (r = -0.41).

The existing preservation methods are difficult to be applied to a large dimension log which is needed for making traditional wooden ship 'Jalur' in Riau Province. Novel techniques to provide the use of readily available species to replace traditional species alternative were investigated. These included infusion and a combination of injection and bandage-wrapping methods for preserving living trees of Balam (Macaranga conifera (Rchb.f. & Zoll.) Müll.Arg.) and Bintangor (Calophyllum soulattri Burm.f.). Water-based boron compounds were applied as wood preservatives. In total, 18 discs from the bottom, middle, and top of four trees and two controls were used. Trees undergoing treatment were also used to see how wood anatomical structure might affect the boron penetration. The overall aim was to identify the best method for use in Jalur manufacturing. The results showed that in infused Balam tree where the hose position for the preservative intake was deep (10-15 cm from the bark), no boron compound was observed in the outer sapwood. Combination of injection and bandage-wrapping method gave higher percentage of boron penetration at bottom and middle of Balam tree. However, infused Bintangor showed 100% boron penetration. The larger vessel diameter, the absence of tyloses, and the simple perforation plates in Bintangor wood were likely to have contributed to the higher penetration of boron. The combination of bandage-wrapping and infusion, or alternatively by infusing the living trees close to the bark, and at as low as position in the stem gives better protection when treatments are applied to living trees.
