Phenylphenalenones, polycyclic aromatic natural products from some monocotyledonous plants, are known as phytoalexins in banana (Musa spp.). In this study, (1) H nuclear magnetic resonance (NMR)-based metabolomics along with liquid chromatography and mass spectrometry were used to explore the chemical responses of the susceptible 'Williams' and the resistant 'Khai Thong Ruang' Musa varieties to the ascomycete fungus Mycosphaerella fijiensis, the agent of the black leaf Sigatoka disease. Principal component analysis discriminated strongly between infected and non-infected plant tissue, mainly because of specialized metabolism induced in response to the fungus. Phenylphenalenones are among the major induced compounds, and the resistance level of the plants was correlated with the progress of the disease. However, a virulent strain of M. fijiensis was able to overcome plant resistance by converting phenylphenalenones to sulfate conjugates. Here, we report the first metabolic detoxification of fungitoxic phenylphenalenones to evade the chemical defence of Musa plants. PMID:26290378

This special editorial for the month of January 2009 is “THE” interview with Professor Tan Sri Dato’ Dzulkifli Abdul Razak, Vice Chancellor of the Universiti Sains Malaysia (USM). He talked to us about the Apex University status that was conferred on 3rd September 2008. While most newspapers and the rest of the media were in frenzy interviewing him that month, MJMS decided to catch up with him on Monday 15th December 2008 just before the celebration at the Dewan Utama, Universiti Sains Malaysia Health Sciences Campus to commemorate the 25th anniversary of the establishment of the Hospital University Sains Malaysia by Yang Berhormat, Minister of Higher Education Datuk Seri Mohamed Khaled Nordin. References to USM as an APEX University are included at the end of this editorial especially for non-USM readers. PMID:22589642

A strong volcanic plume consists of a vertical column of hot gases and dust topped with a horizontal 'umbrella'. The column rises, buoyed by entrained and heated ambient air, reaches the neutral-buoyancy level, then spreads radially to form the umbrella. In classical models of strong volcanic plumes, the plume is assumed to remain always axisymmetric and non-rotating. Here we show that the updraught of the rising column induces a hydrodynamic effect not addressed to date-a 'volcanic mesocyclone'. This volcanic mesocyclone sets the entire plume rotating about its axis, as confirmed by an unprecedented analysis of satellite images from the 1991 eruption of Mount Pinatubo. Destabilized by the rotation, the umbrella loses axial symmetry and becomes lobate in plan view, in accord with satellite records of recent eruptions on Mounts Pinatubo, Manam, Reventador, Okmok, Chaiten and Ruang. The volcanic mesocyclone spawns waterspouts or dust devils, as seen in numerous eruptions, and groups the electric charges about the plume to form the 'lightning sheath' that was so prominent in the recent eruption of Mount Chaiten. The concept of a volcanic mesocyclone provides a unified explanation for a disparate set of poorly understood phenomena in strong volcanic plumes. PMID:19325632
Our Hospital University Sains Malaysia (HUSM) was given the Cabinet approval to exist under the Ministry of Education on 23 November 1982. The Deputy Prime Minister during that period, Yang Berhormat Tun Musa Hitam announced this after the cabinet meeting was held together with the presence of the Yang Berhormat Ministers of Health; and Education, Director of the Public Works Department and the Implementation and Coordinating Unit, Prime Minister's Department. The first patients moved in on 14 March 1983 and the inauguration of HUSM was done on 26 August 1984 by the Duli Yang Maha Mulia Tuanku Ismail Petra Ibni Al-Marhum Sultan Yahya Petra, the Sultan of Kelantan Darul Naim. HUSM celebrated it's 25th anniversary at the Dewan Utama, USM Health Campus on the 15th December 2008 which was inaugurated by Yang Berhormat, Minister of Higher Education Dato' Seri Mohamed Khaled Nordin. USM's Vice Chancellor Professor Tan Sri Dato' Dzulkifli Abdul Razak, Chairman of the USM Board of Directors Tan Sri Dato' Haji Dr. Ani bin Arope, Health Campus Director Professor Dato' Dr. Mafauzy Mohamed, former Campus Director, Dato' Prof Mohd Roslani Abdul Majid, the current and previous Hospital Directors and Deputy Directors since 1983 were present. The achievements of HUSM since its establishment and its vision to fulfil the University's Accelerated Programme for Excellence (APEX) are elaborated. PMID:22589644

In the Molucca Sea region of northeastern Indonesia, the Sangihe and Halmahera arcs are presently in the process of colliding, the earth's only example of a collision between facing volcanic arcs. The collision event is more advanced in the northern Molucca Sea where back-arc thrusting occurs along the Cotobato and Philippine trenches and volcanic centers are inactive and dissected. This paper describes the Sangihe arc, the western arc of the collision. The Sangihe are is approximately 500 km in length extending from the NE tip of Sulawesi to Mindanao, Philippines. The arc comprises over 25 Quaternary volcanic centers, the eight presently active volcanoes being confined to the southern half of the arc. The active volcanic front lies 100-110 km above the top of the west-dipping Benioff zone and volcanoes extend up to 70 km behind the front, thereby defining a volcanic arc overlying earthquakes 100 to 180 km deep. Rock types range from basalt to rhyolite, andesites are dominant. Pyroxene-andesites are common on Sulawesi and at or near the volcanic front from Ruang to Buhias-Pahepa and Buang to Mamanuk. Hornblende-andesites are common at the volcanic front between Mahengetang and Sangihe Island and in centers located well behind the volcanic front. Tholeiitic (TH) suites, defined on the basis of relative degrees of iron enrichment, are confined to the southern volcanic front, lack hornblende, are low-K (K 55 < 1.05), have low Rb/Zr ratios (0.10-0.17), low Ba/Y ratios (3.4-4.9), low Rb/Cs ratios (8-14) and have the highest 87Sr/ 86Sr ratios (0.7039-0.7042). Calcalkaline (CA) suites occur throughout the arc, are low- to high-K (K 55 ≅ 0.6-2.0), have variable Rb/Zr ratios (0.15-0.65) and Ba/Y ratios (4.2-12.4), high Rb/Cs ratios (14-82) and low 87Sr/ 86Sr ratios (0.7035-0.7040). Zr and Y distribution coefficients are lower in TH suites ( DZr = 0.0, DY = 0.2-0.5) than in CA suites ( DZr = 0.0-0.8, DY = 0.3-1.2). Ti initially increases with increasing SiO 2 in some TH
