Stock Market, Corporations and their Regulation: A Few Glimpses into Reality
The paper examines events in three public companies - Enron Corp., Sycamore Networks and Amazon.com, from the perspective of corporate law and securities law. The events are interpreted in terms of the applicable law, and explain how it influences them. In particular, the paper demonstrates how the prevailing loose legal regime for corporations and the stock market-centricity of corporate arrangements give rise to specific varieties of negative behaviour. The paper adopts a critical approach, and is an effort to describe the consequences of the minimalist philosophy underlying corporate and securities regulation
Financial Misconduct, Ethical Theory, and Regulatory Ethics— Promoting Accountability
This paper examines developments in the financial sector and identifies a role for regulatory ethics in promoting integrity and accountability. In this effort, the paper also explores theoretical perspectives in ethics and how they can shape business behavior. Specifically, the article proposes corporate codes of ethics, a mandatory requirement under the New York Stock Exchange Listing Rules, as instruments to promote morality in corporate conduct. Ethics codes, which are internally generated, must be tailored to reflect the experience and made more effective. They can be amplified to specify standards to govern the fiduciary duty of care applicable to executives, personal integrity and accountability. This method can be effective in shaping the moral climate in corporations and in checking misconduct

Canadian Pension Funds: Investments and Role in the Capital Markets and Corporate Governance
The article analyzes Canadian pension funds from the perspectives of corporate governance and the capital markets. It reviews their investment allocations and revenue patterns since the 1990s and identifies significant changes. The article finds that pension funds, as shareholders, have turned more activist and they wield considerable influence on corporate governance. They also contribute to shaping public policy, as evident from the relaxation of the rules on foreign investment and the removal of restrictions on communications among shareholders. The paper predicts that the role of pension funds will likely further expand in the future, given the constant rise in their resources and increased awareness of the need for responsible shareholder activism. Pension funds are ideally suited to be responsible shareholders who can effectively engage with the corporations, particularly in the areas of director elections and promoting corporate accountability

A Review of the Pharmacological and Clinical Profile of Newer Atypical Antipsychotics as Treatments for Bipolar Disorder: Considerations for Use in Older Patients.
Bipolar disorder prevalence rates vary in the older adult population (defined as age ≥ 65 years), ranging from 1% in community dwellers to as high as 8-10% in hospital inpatients. Although older agents, including lithium and valproic acid, offer significant antimanic efficacy, as supported by a recent randomized controlled trial (RCT), there is growing interest in using atypical antipsychotics to treat bipolar disorder in older adults. Newer atypical antipsychotics are of interest based on their tolerability and efficacy in the general adult bipolar population. The aim of this review was to systematically examine efficacy and tolerability of newer atypical antipsychotics for older adult bipolar disorder (OABD). We conducted a systematic search utilizing the MEDLINE, EMBASE, PsycINFO and Cochrane Library electronic databases, with the aim of identifying all RCTs comparing newer atypical antipsychotics approved by the US FDA since 2002 (including brexpiprazole, cariprazine, lurasidone, iloperidone, asenapine, paliperidone, and aripiprazole) with placebo or another comparator, in the treatment of any phase of bipolar disorder (including mania, depression or mixed episodes while used as an acute or maintenance treatment) in older adults (\u3e 65 years). We found no RCT data on any of the examined agents. Hence, we changed our search criteria to include studies with a lower age cut-off (≥ 55 years), as well as the inclusion of post hoc studies. Two post hoc studies on lurasidone suggest its reasonable safety and efficacy profile in the acute and maintenance treatment of OABD; however, there are no pharmacoeconomic data on the use of lurasidone in the treatment of OABD. Research data from open-label studies on oral asenapine and aripiprazole as add-on therapy suggest that these two agents are adequately tolerated and improved symptoms of depression and mania in OABD; hence, there is an urgent need to conduct RCTs on these two agents. Lastly, we found no studies for the treatment of OABD with brexpiprazole, cariprazine, iloperidone, or paliperidone
Adaptive response to low dose of EMS or MMS in human peripheral blood lymphocytes
Human peripheral blood lymphocytes stimulated in vitro for 6 hr were exposed to a low (conditioning) dose of ethyl methanesulfonate (EMS; 1.5 x 10(-4) M) or methyl methanesulfonate (MMS; 1.5 x 10(-5) M). After 6 hr, the cells were treated with a high (challenging) concentration of the same agent (1.5 x 10(-3) M EMS or 1.5 x 10(-4) M MMS). The cells that received both conditioning and challenging doses became less sensitive to the induction of sister chromatid exchanges (SCEs) than those which did not receive the pretreatment with EMS or MMS. They responded with lower frequencies of SCEs. This suggests that conditioning dose of EMS or MMS has offered the lymphocytes to have decreased SCEs. This led to the realization that pre-exposure of lymphocytes to low dose can cause the induction of repair activity. This is a clear indication of the existence of adaptive response induced by alkylating agents whether it is ethylating or methylating in human lymphocytes in vitro
Stereochemistry of gabapentin and several derivatives: solid state conformations and solution equilibria
Gabapentin (1-(aminomethyl)cycloheaxaneacetic acid; Gpn) is a widely used anti-epileptic drug. The target site of action of Gpn remains controversial. Gpn can exist in two isomeric chair forms. The crystal structures of Gpn 1 and eight derivatives, Gpn hydrochloride 2, Gpn lactam 3, Boc-Gpn-OH 4, Ac-Gpn-OH 5, Piv- Gpn-OH 6, Tosyl-Gpn-OH 7, Boc-Gpn-OSu 8 and Boc-Gpn-NHMe 9, are described. The aminomethyl group occupies an axial position in 1, 3, 6 and 7, while it lies in an equatorial orientation in 2, 4, 5 and 8. The structure of Boc-Gpn-NHMe 9 reveals that the crystals contain both chair forms of the derivative in the ratio 0.7:0.3, favouring the aminomethyl group in an axial position. In all cases, the torsional angles about the Cα–Cβ (θ1) and Cβ–Cγ (θ2) bonds of the g-amino acid residue are characteristic of a gauche, gauche (g, g) conformation. In solution, NMR studies establish rapid conformational exchange, as anticipated, at room temperature. Low temperature NMR studies permit conformational freezing and determination of the freeenergy difference between the two 1,1-disubstituted cyclohexane conformers. The largest free-energy difference is observed in the free amino acid (0.38 kcal mol–1), with the most stable conformer having the aminomethyl group in the equatorial position. The free-energy difference between the two forms is significantly reduced in the protected derivatives, with almost equal populations observed in solution for the fully protected neutral derivatives, Boc-Gpn-NHMe and Gpn lactam
Percussion hemoglobinuria - a novel term for hand trauma-induced mechanical hemolysis: a case report
<p>Abstract</p> <p>Introduction</p> <p>Extracorpuscular hemolysis caused by mechanical trauma has been well described in relation to lower extremity use, such as in soldiers and runners. Terms such as "march hemoglobinuria", "foot strike hemolysis" and "runners hemoglobinuria" have previously been coined and are easily recalled. Newer cases, however, are being identified in individuals vigorously using their upper extremities, such as drum players who use their hands to strike the instrument. Given the increased recognition of upper extremity-related mechanical hemolysis and hemoglobinuria in drummers, and the use of hand drumming worldwide, we would like introduce a novel term for this condition and call it "percussion hemoglobinuria".</p> <p>Case presentation</p> <p>A 24-year-old Caucasian man presented with reddish brown discoloration of his urine after playing the djembe drum. Urine examination after a rigorous practice session revealed blood on the dipstick, and 0 to 2 red blood cells per high power field microscopically. The urine sample was negative for myoglobulin. Other causes of hemolysis and hematuria were excluded and cessation of drum playing resulted in resolution of his symptoms.</p> <p>Conclusions</p> <p>The association of mechanical trauma-induced hemoglobinuria and playing hand percussion instruments is increasingly being recognized. We, however, feel that the true prevalence is higher than what has been previously recorded in the literature. By coining the term "percussion hemoglobinuria" we hope to raise the awareness of screening for upper extremity trauma-induced mechanical hemolysis in the evaluation of a patient with hemoglobinuria.</p
