TRADISI MINAHASA TERKAIT DENGAN MAKANAN TRADISIONAL
Authors: Pamantung Rina Palisuan 
Published: September 2019

Food is regarded as important aspects of indigenous culture of Minahasa when viewed from various Minahasa cultural relics that still survive today. In addition, specific Minahasan traditional food is associated with social behavior which is very typical for a particular event in the culture, but still rarely written scientifically, especially in the field of linguistics.Empirical evidence shows that there is an ambiguity (overlap) on the appearance of the name of typical food between the party menu which still contains the original culture of Minahasa like Endo wangko 'holy day' or "Pengucapan" with a menu of food that are commercialized as the name of the food as a restaurant menu, inn or hotel, and vendor menu. In other words, the typical Minahasa food and beverage as a genuine Minahasan culture still appear on the religious function of culture, whereas on the other hand, Minahasan traditional food has appeared on the restaurant menu as a regular menu. The main problem in this study can be formulated as “How does the naming system of food that appears in Minahasa cultural traditions based on myths or folklore that have symbols and myths value and meaningful functioning as a cultural concept of Minahasa?”. The conclusion is the concept of Minahasan culture especially Minahasan traditional food is a dynamic transformation that can be observed in Minahasan culture through the Minahasan traditional food naming system linulut vs non-linulut established or determined by a series of meaning components at the taxonomic hierarchy.Keywords: minahasan traditional food, Minahasan culture.

Objective: Nosocomial infections are those acquired in hospitals or healthcare service units that first appear 48 hours or more after admission or within 30 days after discharge following in-patient care. Knowledge of the bacterial profile and sensitivity patterns of any hospital environment is a key factor in infection control and good antibiotic stewardship.
Material and Methods: This hospital-based cross-sectional study was conducted in the Children’s Emergency Room (CHER) of Enugu State University Teaching Hospital, Enugu, Nigeria. Samples for culture were collected from equipment and hospital surfaces. Antimicrobial susceptibility testing was determined for each isolate by the Agar diffusion method using Standard Nutrient Agar 1 discs.
Results: Bacterial growth was observed in 83 (70.3%) specimens. Staphylococcus aureus (53.4%) was the most common isolate cultured followed by Coagulase-negative Staphylococcus (18.8%), then Escherichia coli (13.9%). Among Staphylococcus aureus isolates, 25.9% were MRSA. Ampicillin resistance of the gram negatives was high. All the Gram-negative isolates were susceptible to Ciprofloxacin and Ceftriaxone.
Conclusion: Staphylococcus aureus, Coagulase-negative Staphylococcus, and Escherichia coli were the commonest isolates. More efforts are needed to ensure improved hygiene standards in order to reduce the burden of nosocomial infections.

Published: September 2019

Background: Diarylethenes are well-known photochromic compounds, which undergo cyclization and cycloreversion reactions between open- and closed-ring isomers. Recently, diarylethene derivatives with photoswitchable fluorescent properties were prepared. They are applicable for fluorescence imaging including bio-imaging. On the other hand, a new system called “excited state intramolecular proton transfer (ESIPT)” is reported. In the system, absorption and emission bands are largely separated due to the proton transfer, hence it showed strong fluorescence even in the crystalline state. We aimed to construct the photochromic system incorporating the ESIPT mechanism.Results: A diarylethene incorporating a fluorescent moiety that exhibit ESIPT behavior was prepared. The ESIPT is one of the examples which express the mechanisms of aggregation-induced emission (AIE). This compound emits orange fluorescence with a large Stokes shift derived from ESIPT in aprotic solvents such as THF or hexane, while it exhibits only a photochromic reaction in protic solvents such as methanol. In addition, it shows turn-off type fluorescence switching in an aprotic solvent and in crystals. The fluorescence is quenched as the content of closed-ring isomers increases upon UV light irradiation.Conclusions: A diarylethene containing an ESIPT functional group was prepared. It showed fluorescent turn-off behavior during photochromism in aprotic solvents as well as in crystalline state upon UV light irradiation. Furthermore, it showed AIE in THF/water mixtures with blue-shift of the emission.
Hoeven diachroon

Published: September 2019

AbstractThe diachrony of Dutchhoeven‘need’This paper presents a diachronic investigation into the semantic and grammatical evolution of the Dutch negative polarity modal auxiliaryhoeven(‘need’). The study is corpus-based, working with representative samples of occurrences of the verb and of its predecessor, the (originally) full verbbehoeven(‘need’), from different stages of Dutch, from Old Dutch until today. It shows how, after the initiation of a tendency to auxiliarize inbehoevenin Early New Dutch (which largely ends again after that period), the short formhoevensplits off from the latter in that same time period and takes the lead as the auxiliary variant from then onwards. It also reveals, however, that in the course of New Dutchhoevenstarts to develop new autonomous uses, in a way comparable to what has happened in the other central modal auxiliaries in Dutch (a case of collective degrammaticalization). Moreover, it shows how, from its emergence onwards, this modal auxiliary develops a wide range of modal and related meanings in a very short time, no doubt due to a strive for (semantic) analogy with the other (and much older) central modals.
River channel width controls blocking by slow-moving landslides in California's Franciscan mélange

Published: September 2019

Abstract. To explore the sensitivity of rivers to blocking from landslide
debris, we exploit two similar geomorphic settings in California's
Franciscan mélange where slow-moving landslides, often referred to as
earthflows, impinge on river channels with drainage areas that differ by a
factor of 30. Analysis of valley widths and river long profiles over
∼19 km of Alameda Creek (185 km2 drainage area) and
Arroyo Hondo (200 km2 drainage area) in central California shows a
very consistent picture in which earthflows that intersect these channels
force tens of meters of gravel aggradation for kilometers upstream, leading
to apparently long-lived sediment storage and channel burial at these sites.
In contrast, over a ∼30 km section of the Eel River (5547 km2 drainage area), there are no knickpoints or aggradation upstream
of locations where earthflows impinge on its channel. Hydraulic and
hydrologic data from United States Geological Survey (USGS) gages on Arroyo Hondo and the Eel River, combined
with measured size distributions of boulders input by landslides for both
locations, suggest that landslide derived boulders are not mobile at either
site during the largest floods (>2-year recurrence) with field-measured flow depths. We therefore argue that boulder transport capacity is
an unlikely explanation for the observed difference in sensitivity to
landslide inputs. At the same time, we find that earthflow fluxes per unit
channel width are nearly identical for Oak Ridge earthflow on Arroyo Hondo,
where evidence for blocking is clear, and for the Boulder Creek earthflow on
the Eel River, where evidence for blocking is absent. These observations
suggest that boulder supply is also an unlikely explanation for the observed
morphological differences along the two rivers. Instead, we argue that the
dramatically different sensitivity of the two locations to landslide
blocking is related to differences in channel width relative to typical
seasonal displacements of earthflows. A synthesis of seasonal earthflow
displacements in the Franciscan mélange shows that the channel width of
the Eel River is ∼5 times larger than the largest annual
seasonal displacement. In contrast, during wet winters, earthflows are
capable of crossing the entire channel width of Arroyo Hondo and Alameda
Creek. In support of this interpretation, satellite imagery shows that
immobile earthflow-derived boulders are generally confined to the edges of
the channel on the Eel River. By contrast, immobile earthflow-derived
boulders jam the entire channel on Arroyo Hondo. Our results imply that lower drainage area reaches of earthflow-dominated catchments may be particularly prone to blocking. By inhibiting the upstream
propagation of base-level signals, valley-blocking earthflows may therefore
promote the formation of so-called “relict topography”.

Background Mastectomy in male transgender patients is an important (and often the first) step toward physical manhood. At our department, mastectomies in transgender patients have been performed for several decades.
Methods Recorded data were collected and analyzed for all male transgender patients undergoing mastectomy over a period of 24 years at our department.
Results In total, 268 gender-reassigning mastectomies were performed. Several different mastectomy techniques (areolar incision, n=172; sub-mammary incision, n=96) were used according to patients’ habitus and breast features. Corresponding to algorithms presented in the current literature, certain breast qualities were matched with a particular mastectomy technique. Overall, small breasts with marginal ptosis and good skin elasticity allowed small areolar incisions as a method of access for glandular removal. In contrast, large breasts and those with heavy ptosis or poor skin elasticity often required larger incisions for breast amputation. The secondary correction rate (38%) was high for gender reassignment mastectomy, as is also reflected by data in the current literature. Secondary correction frequently involved revision of chest wall recontouring, suggesting inadequate removal of the mammary tissue, as well as scar revision, which may reflect intense traction during wound healing (36%). Secondary corrections were performed more often after using small areolar incision techniques (48%) than after using large sub-mammary incisions (21%).
Conclusions Choosing the suitable mastectomy technique for each patient requires careful individual evaluation of breast features such as size, degree of ptosis, and skin elasticity in order to maximize patient satisfaction and minimize secondary revisions.

Background The mandible is an important structure that is located in the lower third of the face. Large mandibular defects after tumor resection cause loss of its function. This study assessed the outcomes and tumor recurrence after immediate mandibular reconstruction using a free fibula osteocutaneous flap following radical resection of ameloblastoma.
Methods This is a retrospective non-randomized study of outcomes and tumor recurrence of all patients diagnosed with mandibular ameloblastoma from August 1997 until August 2017 (20 years) requiring free fibula osteocutaneous flap reconstruction at a single institution. The patients were identified through an electronic operative database; subsequently, their medical records and photo documentation were retrieved.
Results Twenty-seven patients were included in this study. Eighteen patients were male, while nine were female. The majority of the patients (48.1%) were in their third decade of life when they were diagnosed with ameloblastoma. All of them underwent radical resection of the tumor with a surgical margin of 2 cm (hemimandibulectomy in cases with a large tumor) and immediate mandibular reconstruction with a free fibula osteocutaneous flap. Two patients required revision of a vascular anastomosis due to venous thrombosis postoperatively, while one patient developed a flap recipient site infection. The flap success rate was 100%. There was no tumor recurrence during a mean follow-up period of 5.6 years.
Conclusions Mandibular ameloblastoma should be treated with segmental mandibulectomy (with a surgical margin of 2 cm) to reduce the risk of recurrence. Subsequent mandibular and adjacent soft tissue defects should be reconstructed immediately with a free fibula osteocutaneous flap.

Published: September 2019

Background Various surgical management methods have been proposed for ischial sore reconstruction, yet it has the highest recurrence rate of all pressure ulcer types. A novel approach combining the advantages of a perforator-based fasciocutaneous flap and a muscle flap is expected to resolve the disadvantages of previously introduced surgical methods.
Methods Fifteen patients with ischial pressure ulcers with chronic osteomyelitis or bursitis, who underwent reconstructive procedures with an inferior gluteal artery perforator (IGAP) fasciocutaneous flap and a split inferior gluteus maximus muscle flap from January 2011 to June 2016, were analyzed retrospectively. The split muscle flap was rotated to obliterate the deep ischial defect, managing the osteomyelitis or bursitis, and the IGAP fasciocutaneous flap was rotated or advanced to cover the superficial layer. The patients’ age, sex, presence of bursitis or osteomyelitis, surgical details, complications, follow-up period, and ischial sore recurrence were reviewed.
Results All ischial pressure ulcers were successfully reconstructed without any flap loss. The mean duration of follow-up was 12.9 months (range, 3–35 months). Of 15 patients, one had a recurrent ulcer 10 months postoperatively, which was repaired by re-advancing the previously elevated fasciocutaneous flap.
Conclusions The dual-flap procedure with an IGAP fasciocutaneous flap and split inferior gluteus maximus muscle flap for ischial pressure ulcer reconstruction is a useful method that combines the useful characteristics of perforator and muscle flaps, providing thick dual padding with sufficient vascularization while minimizing donor morbidity and vascular pedicle injury.

Published: September 2019

Background The objectives of this study were to design polycaprolactone nanofibers with a radial pattern using a modified electrospinning method and to evaluate the effect of radial nanofiber deposition on mechanical and biological properties compared to non-patterned samples.
Methods Radially patterned polycaprolactone nanofibers were prepared with a modified electrospinning method and compared with randomly deposited nanofibers. The surface morphology of samples was observed under scanning electron microscopy (SEM). The tensile properties of nanofibrous mats were measured using a tabletop uniaxial testing machine. Fluorescence-stained human bone marrow stem cells were placed along the perimeter of the radially patterned and randomly deposited. Their migration toward the center was observed on days 1, 4, and 7, and quantitatively measured using ImageJ software.
Results Overall, there were no statistically significant differences in mechanical properties between the two types of polycaprolactone nanofibrous mats. SEM images of the obtained samples suggested that the directionality of the nanofibers was toward the central area, regardless of where the nanofibers were located throughout the entire sample. Florescence images showed stronger fluorescence inside the circle in radially aligned nanofibers, with significant differences on days 4 and 7, indicating that migration was quicker along radially aligned nanofibers than along randomly deposited nanofibers.
Conclusions In this study, we successfully used modified electrospinning to fabricate radially aligned nanofibers with similar mechanical properties to those of conventional randomly aligned nanofibers. In addition, we observed faster migration along radially aligned nanofibers than along randomly deposited nanofibers. Collectively, the radially aligned nanofibers may have the potential for tissue regeneration in combination with stem cells.
