Enabling AI in synthetic biology through Construction File specification.

The Construction File (CF) specification establishes a standardized interface for molecular biology operations, laying a foundation for automation and enhanced efficiency in experiment design. It is implemented across three distinct software projects: PyDNA_CF_Simulator, a Python project featuring a ChatGPT plugin for interactive parsing and simulating experiments; ConstructionFileSimulator, a field-tested Java project that showcases 'Experiment' objects expressed as flat files; and C6-Tools, a JavaScript project integrated with Google Sheets via Apps Script, providing a user-friendly interface for authoring and simulation of CF. The CF specification not only standardizes and modularizes molecular biology operations but also promotes collaboration, automation, and reuse, significantly reducing potential errors. The potential integration of CF with artificial intelligence, particularly GPT-4, suggests innovative automation strategies for synthetic biology. While challenges such as token limits, data storage, and biosecurity remain, proposed solutions promise a way forward in harnessing AI for experiment design. This shift from human-driven design to AI-assisted workflows, steered by high-level objectives, charts a potential future path in synthetic biology, envisioning an environment where complexities are managed more effectively.

Differentiating Cerebral Toxoplasmosis and Tumor Recurrence by Thallium-201 Single-Photon Emission Computerized Tomography in a 28-Year-Old Female with Astrocytoma.

Cerebral toxoplasmosis is an opportunistic infection that, by itself, is difficult to differentiate from cerebral neoplasms by conventional neuroimaging. It rarely occurs concurrently in patients with a primary brain tumor but when it does, it makes diagnosis and management more difficult. This is a case of a 28-year-old female, diagnosed with a right frontal pleomorphic xanthoastrocytoma with several recurrences, treated with surgery, radiation, and chemotherapy. Three years from diagnosis, the patient was readmitted for generalized body weakness, fever, and a decrease in sensorium. A repeat cranial magnetic resonance imaging showed multiple enhancing lesions in both cerebral hemispheres and in the posterior fossa. Serum toxoplasma IgM and IgG antibody titers were elevated. Single-photon emission computerized tomography (SPECT) with thallium-201 did not show increased tracer uptake in these lesions, favoring toxoplasmosis over tumor recurrence. The patient was treated with trimethoprim-sulfamethoxazole with significant improvement. This is a rare account of cerebral toxoplasmosis arising in the setting of astrocytoma. This is also the first case report to demonstrate the value of thallium-201 SPECT in differentiating central nervous system infection from tumor recurrence, which is pivotal in management. More studies exploring the use of thallium-201 SPECT in distinguishing central nervous system infections from glioma and other malignant tumors should be undertaken to maximize this imaging modality in neuro-oncology practice.

Primary headache research output and association with socioeconomic factors in Southeast Asia: a bibliometric analysis.

BACKGROUND: Although headache is one of the most common neurologic conditions with a high disease burden, primary data on headache research from Southeast Asia (SEA) was hypothesized to be inadequate. This study aimed to evaluate research productivity among the different countries in SEA and to determine the association between specific bibliometric indices and socioeconomic factors. METHODS: A systematic search was conducted until June 10, 2020 in Scopus, PubMed, Embase, Cochrane Central Register of Controlled Trials, and Index Medicus for South-East Asia Region to include all primary headache studies on migraine, tension-type headache, and trigeminal autonomic cephalalgia, with at least one author affiliated with a SEA country. Bibliometric indices, such as the number of publications and PlumX metrics, were obtained and correlated with the country-specific socioeconomic factors. RESULTS: We identified 153 articles. Most of the publications (n = 43, 28.1%) were epidemiologic studies and case reports/series (n = 25, 16.3%). Migraine was the most studied primary headache subtype. Malaysia, Singapore, and Thailand were the major contributors to primary headache research in SEA. Only the percent gross domestic product for research and development correlated significantly with research productivity. CONCLUSION: Despite the high global burden of disease, research productivity on primary headache was low in SEA. The move towards a knowledge-based economy may drive research productivity in SEA.
