<strong>Dynamics of Sedimentation Process at Riko River Estuary, Balikpapan Bay.</strong> Development of the marine facilities (i.e. port, workshops, laboratories, etc)  for Indonesian Research Vessels and National Center for Marine Research in the proposed National Science Technopark (NSTP) Maritime Region at District of Penajam Paser Utara, East Kalimantan Province, needs to understanding the dynamic of waters physical environment. Due to the NSTP-Maritime region located at Riko River as part of Balikpapan Bay waters, it needs an ocean interaction study between open sea (Balikpapan Bay) and Riko River waters. This study used a 2D-Hydrodynamic Model  for  Riko River and Balikpapan Bay waters and adjacent sea. The model simulated the hydrodynamic conditions on the waters and   furthermore predicted   the mud transport in  September - November 2016 using the river flow and total suspended sediment data collected in November 2016. The model results showed that the average of sediment load movement due to the dynamic of waters at the estuary is   ± 4,25 x10-3 kg per second or ± 367,7 kg per day. This preliminary study hopefully  can explain the shallowing  processes in mouth of Riko River.

Catch Rates

This research undertaking was conducted in Aparri, Cagayan, particularlyat the Cagayan River Estuary. The study generally characterized the catch rates and socio–economic dynamics of the filter net fisheries of the said estuary. The study utilized of questionnaires to obtain the data. It also considered personalinterviews and observation to validate the data. Results revealed that majorityof the respondents were married, have children ranging from 1-4, aged 26-40,finished elementary level of education, with no extended family. Majority of therespondents were engaged in fishing without alternative source of income. Ongear species accounting, most of the drift filter net fishers consumed 1-2 hoursper haul with alamang catch of 11-20 cans per haul and 9-10 hours per haulwith 1-5 kilograms per haul for the stationary filter net fishers. Majority of thefishers have 3-4 hauls per day. On sales and sharing scheme of the drift filter netfishers, majority of the drift filter net fishers had sales of 10,000 and below perfishing trip, majority of the fishermen had a share of 500.00 per fishing trip. Asto the respondents’ involvement in community activities, most of them joinedcommunity activities despite the fact that they do not hold any position in thecommunity. There were 19 identified species that were caught by the drift filternet (DFN) and stationary filter net (SFN) for the months of May & June, withrespect to moon phases. Catch per unit effort of “saplar” was higher than that of“banwar”.Keywords: Aquatic Ecology, catch, effort, Filter Net Fisheries, descriptive design,Cagayan, Philippines

Hormonal Therapies

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.

Preliminary Study

A new strain of mice, which had arisen by mutation from a dystrophic mouse colony was designated ‘mdx’, because the genetic defect, which manifests itself in brief periods of muscle destruction followed by episodes of muscle regeneration appears to be X-linked. Further studies of histopathological changes in muscle from ‘mdx’ mice at the light microscopic or electron microscopic levels have been published, but only one preliminary study has been on the tibialis anterior (TA) of ‘mdx’ mice less than four weeks old. Lesions in the ‘mdx’ mice vary between different muscles, and centronucleation of fibers in all muscles studied so far appears to be especially prominent in older mice. Lesions in young ‘mdx’ mice have not been studied extensively, and the results appear to be at variance with one another. The degenerative and regenerative aspects of the lesions in the TA of 23 to 26-day-old ‘mdx’ mice appear to vary quantitatively.

Preliminary Study

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.
