Lithofacies and depositional environment spanning the Cretaceous-Paleogene boundary on the New Jersey coastal plain
No full textThe sedimentary record spanning the Cretaceous-Paleogene (K/Pg) boundary was examined in outcrop and in seven cores recovered from a 50 km long transect along the outcrop belt on the New Jersey coastal plain. The objectives were to: (1) conduct a high-resolution study of the K/Pg lithofacies, (2) document spatial and temporal changes in composition and texture of the sediments, and (3) interpret any changes in the depositional environment across this important geological boundary when a mass extinctions occurred. Analyses include core description, textural, petrographic, microprobe, and XRD analyses. Five lithofacies were interpreted in the Upper Cretaceous sediments and three lithofacies were recognized from the lowermost Paleogene deposits. Microprobe studies show the chemistry of Upper Cretaceous and lowermost Paleogene glauconite are identical (~7-8% K2O), but their color difference may suggest different redox condition. XRD analyses show the Upper Cretaceous clay contains more land-derived detritus than the lowermost Paleogene clay. The following sequence of events is interpreted from the sediment record spanning the K/Pg boundary: (1) deposition in near-shore setting and slow sedimentation in middle shelf when sea level was falling, albeit still shelfal depth; (2) deposition of K/Pg lithofacies when sea level was falling possibly creating a diastem but not a sequence boundary, per se; (3) a transgression above the K/Pg boundary; and (4) deposition in middle shelf possibly with decreased ocean productivity and a more reducing environment. There is no sedimentological evidence above the K/Pg boundary, suggesting tsunami-related deposition associated with a bolide impact. Either a tsunamite was eliminated by bioturbation, or NJCP was too far from the impact site to be affected. A transgressive lag, instead, was formed by normal sedimentation during the subsequent transgression in the early Paleocene.M.S.Includes bibliographical referencesby Hendra Wahyud

Analysis of Hendra Virus Fusion Protein N-Terminal Transmembrane Residues
Get PDFHendra virus (HeV) is a zoonotic enveloped member of the family Paramyoxviridae. To successfully infect a host cell, HeV utilizes two surface glycoproteins: the attachment (G) protein to bind, and the trimeric fusion (F) protein to merge the viral envelope with the membrane of the host cell. The transmembrane (TM) region of HeV F has been shown to have roles in F protein stability and the overall trimeric association of F. Previously, alanine scanning mutagenesis has been performed on the C-terminal end of the protein, revealing the importance of β-branched residues in this region. Additionally, residues S490 and Y498 have been demonstrated to be important for F protein endocytosis, needed for the proteolytic processing of F required for fusion. To complete the analysis of the HeV F TM, we performed alanine scanning mutagenesis to explore the residues in the N-terminus of this region (residues 487–506). In addition to confirming the critical roles for S490 and Y498, we demonstrate that mutations at residues M491 and L492 alter F protein function, suggesting a role for these residues in the fusion process

Popularity, media and electability: study of Alfiansyah Komeng in the election of members of the Regional Representative Council (DPD) in West Java / Hendra, Mudiyati Rahmatunnisa and Ratnia Solihah
Get PDFIn 2024 Indonesia will again hold general elections to fill executive and legislative positions. One of the legislative member elections was to elect members of the Regional Representative Council (DPD) as the institution representing each province in Indonesia. An interesting phenomenon in this election was Alfiansyah Komeng's election as a DPD member representing West Java Province, surpassing the other candidates with the highest vote acquisition of 5,399,699 votes. Using a qualitative approach and data collection techniques through literature studies, the results showed that Komeng's electability was based on popularity, integrity, people's dissatisfaction with conventional politics, photos on ballot papers and the benefits of holding elections simultaneously. Meanwhile, according to the author, the media and the message conveyed are minor factors in Komeng's choice
Biological Activities and Flavonoid Content of Different Parts of Phaleria Macrocarpa (Scheff.) Boerl Fruit Extracts
Get PDFPhaleria macrocarpa (Scheff.) Boerl (Family Thymelaceae) posses several bioactivities and is used as traditional medicine in Indonesia. Investigation on antioxidant, anti-inflammatory and antimicrobial activities are still lacking. The aims of this study were therefore to determine those biological activities of methanolic, ethyl acetate, hexane and hot water extract from pericarp, mesocarp, and seed of P. macrocarpa fruit and quantitative analysis of total phenolics and flavonoids present in the various bioactive extracts. The methanolic, ethyl acetate and hexane extracts of pericarp showed free radical scavenging activity (71.9±1.9, 88.1 ± 2.5 and 78.2± 1.7%) at concentration of 300 μg/ml and these results were lower as compared to butylated hydroxytoluene (BHT), ascorbic acid and α-tocopherol (antioxidant standards). The methanolic, ethyl acetate and hot water extracts of pericarp showed high reducing power with values 92.5±0.1, 84.7±0.3 and 91.9±0.1%, respectively at 300 μg/ml. All parts of P. macrocarpa fruit showed low to moderate level of nitric oxide inhibitory activity in IFN-γ/LPS activated RAW 264.7 cell line with values of 15.6±1.0% to 75.0±0.7% at concentration of 200 μg/ml without cytotoxic to the cells. In addition, methanol and ethyl acetate extract of P. macrocarpa fruits at 1.5 and 3 mg/disc showed variable inhibitory activity against both Gram-positive and Gram-negative bacteria with inhibition zone diameters ranging from 0.32-2.33 cm exclusive of paper disc (0.6 cm). While, ethyl acetate extract of P. macrocarpa fruits at 3 mg/well showed variable inhibitory activity against all fungi tested with inhibition zone diameters ranging from 0.4-2.13 cm exclusive of well diameter (0.6 cm).
The total phenolic contents analysis showed that ethyl acetate extract of seed contained the highest amount of total phenolic at 60.94±0.81 mg GAE/g DW while the lowest amount was observed in hexane extract of pericarp at 32.97±0.69 mg GAE/g DW. Furthermore, methanolic extract of pericarp contained the highest amount of total flavonoids with a value of 161.35±1.59 mg rutin equivalent/g DW and the lowest was observed in hexane extract of seed with a value of 9.66±0.07 mg rutin equivalent/g DW. Quantitative analysis of flavonoid compounds from P. macrocarpa fruit (pericarp, mesocarp and seed) were performed by using reversed-phase high performance liquid chromatography (RP-HPLC) technique. The results showed that kaempferol, myricetin, naringin, quercetin and rutin were present in all different part of P. macrocarpa fruit. Thus, the present results showed that P. macrocarpa fruit (pericarp, mesocarp and seed) poses antioxidant, anti-inflammatory and antimicrobial activities might be due to the present of flavonoid and phenolic compounds
